Abstract

In this study, the validity and applicability of the multipurpose fishway which has been constructed for the upstream migration of fish at Chuksan river in Uljin is assessed and analyzed by a commercial software. The upper slab types of fishway in this investigation are reinforced concrete slab (S1 type) and reinforced concrete slab with steel plate (S2 type). The three different sizes of subway passage ($0.8m{\times}0.1m$, $0.8m{\times}0.2m$, $0.8 m{\times}0.3m$) and velocities (0.6 m/s, 1.2 m/s, 1.8 m/s) of Chuksan fishway was investigated and compared for the Chuksan in government design code. The analysis showed that the maximum stress and bending moment of S1 type decreased 1~21 % and 12~27 % compared to the Chuksan in government design code, respectively. Also, the maximum stress of and bending moment of S2 type decreased 11~32 % and 27~39 %. From the numerical analysis, it was found that the S2 type was greatly effective and the subway passage size of $0.8m{\times}0.2m$ was most safe. This result can be utilized to be the basic data for design of the Multipurpose fishway.
