重力式桥台开裂原因的有限元分析与加固措施

Crack Finite Element Analysis and Reinforcement for Gravity Abutment

本文针对公路上中、小桥台普遍存在的开裂问题,结合实际工程,借助大型通用有限元软件ANSYS对某公铁立交桥斜交U型重力式桥台在侧墙与前墙接缝处开裂的原因进行了分析,且提出了开裂成因和防治办法,供设计、施工参考.

Cracking exit in lots of gravity abutments. Combing with the project, the crack reasons is analyzed by way of FEM in this paper. According to this, the reinforcement scheme and serval suggestions for designing and construction of gravity abutment is put forward.
