暗板桥薄壁式桥台背墙受力分析及承载力验算

Analysis of Load-Bearing of Thin-Walled Abutment Back for Slab Bridge with Top-Fill,and Checking Computation of Bearing Capacity

针对一座高填土暗板桥薄壁式桥台的情况,对背墙进行了受力分析,并进行了抗弯承载力和抗剪承载力的验算,以校核背墙的构造尺寸及配筋是否满足要求。

Aiming at thin - walled abutment of slab bridge with top - fill, the paper analyzes the load bearing of abutment back, and makes checking computation of bearing capacities for bending resistance and shearing resistmace in order to examine the constructed sizes of back and if the reinforcement satisfies needs.
