This paper presents the slope wall technique using soil improvement material for reinforced soil slope through laboratory scale model tests, and verifies the experimental results comparing with numerical analysis. In additional, case study in field has performed to investigate the deformation of reinforced soil slope for 6 months. As a result of laboratory scale model test, numerical analysis, and case study, the reinforcement effect of the slope wall technique using soil improvement material is sufficient to be constructed as reinforced soil slope. The technique shows the stable ratio (0.4%) of horizontal to vertical deformation in the surface loading.

This study was conducted to grasp the effect of afforestation of cut slope using coir blocks on the improvement of scenery and the management of non point pollution source. Total four experimental tanks such as general soil slope, coir blocks, installation slope, slope refilling the inside of coir blocks slope with pebble, slope refilling the inside of coir blocks with soil and plant were installed, pollution source water was supplied and the possibility of reduction management of non point pollution source was analyzed at four items of COD, SS, T-N, T-P and main results drawn from this study are as follows. In conclusion, biodegradable materials like coir blocks and soil and plant layers are judged to be helpful in reduction management of non point pollution source inflowing to water space from land area. Thus, the reduction of non point pollution source occurring at land area is thought to be fully controlled at the cut slope, the space prior to inflowing to water ecological space like a stream or a swamp area.

In order to seek a efficiency of site cooperation and slope stabilization in a rock sloping work, it would rather take into consideration, in its importance, a concurrent performance of civil works and landscaping works than give any part a special priority. It can enable us to achieve an expanded scope of landscaping works and improvement of slope scenery via this sort of cooperation. However, this can not be achieved without assurance on the slope stabilization and scenic view of the project owner, and further via this cooperation, environmentally familiar works can be performed, becoming natural environment and minimizing damages on surrounding scenery and environment. It is foreseeable that improvement of functions of civil equipment, introduction of technology and development of landscaping materials can facilitate an improvement in the betterment of slope scenery. Landscaping related parties need to enhance their understanding of rock sloping and scenic view based on knowledge on the fundermental understanding of slope stabilization and on the base rock characteristics.

Purpose: The ramp is an important facility for the barrier free access and vertical circulation of users of various buildings, including users of walker, wheelchair users, stroller users, and baggage carriers. The installation standards for ramps in Korea have various problems during construction and BF certification. It is necessary to improve the criteria for ensuring practical mobility and safety. Method: Korean standard, International Standard(ISO 21542, 2011), German Standard(DIN 18040-1, 2010), Austrian Standard(OENORM B 1600, 2017), Swiss Standard(Norm SIA 500, 2009), Canadian Standard(Building Standards Guide, 2017), American Standard(ADA Standards, 2010) were investigated and analyzed. A comprehensive improvement of the ramp installation standards is proposed. Results: The ramp is a necessary facility for the barrier free access and vertical circulation of the disabled. It shall be installed with comprehensive consideration of the appropriate slope of the ramp, the distance of the continuous slope, the handle and upstand for pedestrian safety. In order to improve convenience, setting the proper slope and limiting the length of the slope are very important, and improvements are required to the levels presented by international and foreign standards. The unclear standards of Korean law and BF certification standards should be clearly improved so as not to be misinterpreted in construction and Barrier Free Certification. Implication: International and foreign standards should be reviewed to ensure practical mobility and safety. And comprehensive improvement measures should be presented through continuous research.

Continuous road improvement is required by situation that need link between cities by special quality that is our country's topography enemy that most of country have consisted to mountain district. According to this, occurrence of large cutting slope is formed necessarily Cutting slope are very weak real condition because of concentrative downpour and can know easily by example of typhoon Rusa. This study did helpful in slope design and carrying out suitable reinforcing method.

Mountain trails play an important role in the daily life and health of the citizens, and also are major areas for recreation operators strive to balance the needs of pedestrian with the needs of wildlife and health improvement. In this view point, this research aims at analyzing the slope of mountain trails using mobile GPS and suggesting the suitable path to citizens for improving health. The result shows that the trail slope analysis by using mobile GPS could be effectively evaluated the degree of walk difficulty.

Recently, disaster that is earthquake, sever rainstorm and the tidal wave were increased by abnormal weather. These influence which is the slope stability of the completed slope as well as under construction slope is affected by disaster. But the management standard for the construction slope is incomplete. Also, the standard connected with construction slope is not integrated with the important public paper organic enemy and it is duplicated and the standards which conflict are being scattered. In this research which it sees consequently the inside and outside of the country construction slope the maintenance civil official relation law and standard investigation it leads and the problem point and a improvement program of management criterion and to sleep the construction slope which is suitable in domestic actuality it prepares and propose.

In this study, laboratory test, program analysis, and test construction in the field were performed to utilize Supplementary Cementitious Material (SCM) developed by recycled resources for slope reinforcement as slope improvement material for aging reservoir, and the results were analyzed. As results of the laboratory test, it was analyzed that the mixing ratio of SCM was appropriate by 9 %, and the coef. of permeability was decreased by about 10,000times, indicating a value close to that of the waterproof material applied in Korea. In addition, as a result of program analysis and test construction, it was analyzed that seepage did not occur in the part of reinforced using SCM and showed a higher safety facto r than domestic criteria. Therefore, since it shows sufficient waterproof and reinforcing effects in aging reservoir, it is judged that the slope improvement using SCM can replace the cement for repair and reinforcement method.

Test application of revegetation measure was made on the roadside slope damaged by Gimcheon-Eomo national road improvement project in a bid to prevent the soil from being washed out as well as to restore the ecological environment, and the survey for assessing the effect of slope revegetation measures was conducted, beginning Sep 7 through Sep 20, 2006. In the wake of comprehensive reviewing and evaluating the surrounding topographic environment, physical and chemical characteristics of soil, germination of revegetation plants, analysis of bio mass, covering ratio and the plants appeared, revegetation measure C was found to have been most effective and desirable for further application in the area. Viewing the specific applicability by the area, revegetation measure C and C-1 appeared to be appropriate for blasting rock slope and ripping rock slope as they are efficient in preventing the slope from being washed out and in early revegetating. And revegetation measure B deemed to be effective to blasting rock slope or ripping rock slope as an alternative. And for cut slope, vegetation measure C-2 was judged to be more effective than measure D or E, while measure C-3 would be appropriateto embankment slope.
