摘要
对于拱座台阶式基础,传统的计算方法没有考虑基础背面地基的作用,可能导致基底应力计算结果偏于保守。通过建立三维有限元仿真计算模型,得出台阶式基础的实际应力分布情况,其结论可为拱桥基础的设计及施工提供参考。
When use the traditional methods to calculate the stress of step - shaped foundation of arch abutment, the effect of Subgrade, in contact with back surface of foundation, was neglected, which could produce more conservative calculated results of foundation stress. Estabhshing a three - dimensional finite element simulation model can help to draw out the practical stress dismbution of step - shaped foundation, which could be the reference to the designing and constructing of foundation.
