Analysis of Design Parameters for Power Plant Breakwater Channels Using Geotextile Containment
Kim, Sung-Hwan ; Oh, Young-In ;
Journal of the Korean Geosynthetic Society, volume 7, issue 3, 2008, Pages 1~7
The geotextile tube shall be sewen with geotextile longitudinally in the shape of hose and it shall be filled hydraulically through filling ports at the proper intervals to construct structure. Geotextile container shall be sewen after spreading of geotextile on the split barge and sealed shut after the filling soil, and then moved and positioned at the required position. And the geotextile container passes through the bottom of barge by opening split barge and drops to the seabed to form structure. This structure for the
project, UAE and we would propose that geotextile containment for core material of power plant breakwater to be constructed for lower bunds with containers up to -4.0m and do upper parts with the structures of tube up to 0.0m. For the application of proposed geotextile containment, review on stability of breakwaters and design consideration were adopted. The evaluation on stability of geotextile containment was classified by 3 items, internal design consideration for material selection, reviews on stability for individual and global structure. In this research, the geothermal analysis was performed to estimate the geothermal behavior of central breakwater. Central breakwater is located boundary of intake and outfall channel, it is mean that the central breakwater is thermal boundary of intake low temperature sea water and outfall high temperature sea water. Therefore, it is required to be designed a low permeability to ensure no mix of intake and outfall waters.
The Study of Numerical Analysis on Failure Behavior of Reinforced Soil Wall
Kim, Young-Min ;
Journal of the Korean Geosynthetic Society, volume 7, issue 3, 2008, Pages 9~16
This paper is concerned with the numerical evaluation of the failure behavior of reinforced soil walls based on the elasto-plastic theory. At first, the basic analysis on the failure behavior of reinforced soil walls are discussed. Parametric study of the major factors influencing the failure behavior is conducted by FEM. The objectives are to identify and evaluate the major facts influencing the failure mode of reinforced soil walls. The results of the parametric study on the failure behavior due to soil friction angle, reinforcement type, and reinforecement length are analysed.

This study is conducted to investigate the possibility of the utilization of the mixed soil formed by mixing stone sludge, bentonite, and residual soil as a soil sealant sustaining both stability and capacity in the barrier system. A series of tests were performed on the mixed soils to evaluate basic properties such as compaction, compressive strength, permeability and CBR of these materials. The results indicates that as the stone sludge content increases, the optimum moisture content increases a little, but the maximum dry density decreases. The compressive strength and CBR decrease, and the cohesion, internal friction angle and expansion ratio increase. When the bentonite content increases, the maximum dry density decreases, and the optimum moisture content, compressive strength and cohesion, internal friction angle, CBR and expansion ratio increase. Mixing ratio of the mixed soil contained with the stone dust more than 10% and the bentonite less than 10% satisfies the standard of the permeability coefficient as the soil sealant.

In this research, the characteristics of settlement and consolidation behavior of the composite ground formation reinforced by Recycled-Aggregate Porous Concrete Pile (RAPP) were evaluated by conducting a series of laboratory chamber tests. The effect of settlement reduction was verified by comparing the settlement of the composite ground formation with that of the unreinforced ground. In addition, it was studied how much the RAPP can accelerate consolidation in assessment of the degree of consolidation in the composite ground formation. The amount of settlement reduction was decreased with an increase on surcharge pressure, but it was greater than that of the SCP method. The RAPP and the SCP showed a similar rate of consolidation.
Deformation Analysis of Excavated Behind Ground by The Artificial Displacement Method (II) - Numerical Analysis and Application -
Yun, Jung-Mann ;
Journal of the Korean Geosynthetic Society, volume 7, issue 3, 2008, Pages 31~40
The deformation behavior of the excavated behind ground due to the displacement shape of retention walls is predicted by numerical analysis, which can be performed using the artificial displacement method with elasto-plastic constitutive model. The displacement shape of the behind ground around the retention wall is similar to the displacement shape of the retention wall. However, far from the retention wall, it changes to the displacement shape of cantilever. The deformation (the settlement, the lateral movement) of the excavated behind ground can be decreased by restraining the upper displacement of the retention wall. The displacement shape of the retention wall due to excavation affects on the plastic failure zone and decreasing zone of stability of the excavated behind ground.

Journal of the Korean Geosynthetic Society, volume 7, issue 3, 2008, Pages 41~49
This study was carried out the model experiment in laboratory to evaluate the bearing capacity improvement of soft ground as altered constraint condition of reinforcements according to geotextile, georid, steel bar. As a results, the value of BCR was increased linearly as improvement of the stiffness of reinforcements, and the factor governed the increasement of BCR was the increasement of frictions between reinforcement and clay as far as the constrain conditions increased until T=85.6kg. Moreover, An angle of inclination,
, between reinforcement and horizontal surface was distributed from
for Geotextile, from
for Geogrid and from
for steel bar. A radius of heaving, r, of clay ground by vertical weight at side was distributed from 0.6m to 0.7m for Geotextile, from 0.5m to 0.8m for Geogrid, and from 2.4m to 3.0m for steel bar. In case of steel bar, r was 4 times that of Geotextile.
