3D해석에 의한 개량형 CIP벽체의 거동

초록

As an earth-retaining wall, CIP(Cast in Place)method is widely used for excavation in urban area. This research presented 3-D analysis results using improved CIP in which H beam is replaced by steel plate. Use of H beam in CIP is entirely for installation of wale and strut. In this research lateral movement of improved CIP wall is analysed and compared to those of CIP that is widely used at present. From the comparison of lateral deflection of the wall, the difference is negligibly small. And it was confirmed that improved CIP could be used in practice without any problem.
