버트레스를 설치한 선반식 옹벽에 관한 연구

This study is a study on the behavior of buttress retaining wall with relieving platform. As a result of analyzing and comparing earth pressure, shearing force, and moment that acts to each cantilever retaining wall, it was found that both buttress retaining wall with relieving platform and general retaining wall with relieving wall burdens vertical earth pressure and their earth pressure that acts to retaining wall is alleviated relatively significantly compared to cantilever retaining wall. Especially in buttress retaining wall with relieving platform, buttress restricts shelf and thus shearing force and moment that retaining wall burdens from earth pressure were relatively lower than cantilever retaining wall and retaining wall with relieving platform. With respect to conduction, buttress retaining wall with relieving platform appears relatively more stable.
