双排桩基托梁∏形结构计算理论探讨

Discussion on the calculation theory of double row pile bridle trimmer ∏ shape structure

根据桩基托梁挡土墙支挡结构的受力特点,对其设计理论进行讨论,提出两种计算模式假设:抗滑型和承载型桩基托梁挡土墙,并结合襄渝线增建二线工程实例进行数值模拟分析,验证假设合理性,为支挡结构的计算理论提供参考依据。

According to the stress characteristics of pile bridle trimmer earth-retaining wall structure, its design theory was discussed. Two cal- culation model assumptions were proposed, i.e. skid resistance and bearing pile bridle trimmer earth-resistance wall. Combined with the nu- merical modeling analysis of the additional second engineering example of Xiang-Yu line, the assumption rationality was checked, which pro- vided reference for supporting and retaining structure theory.
