软土基坑双排桩支护结构的变形性状分析

摘要

With its unique advantages, double-row piles supporting structure has been more and more widely used. However, its computation theory still needs to be further improved. Combined with specific projects in soft-soil soil, the results of the model recommended by code and the numerical calculation model were discussed, and the results were compared with the experimental results. Through the analysis, the following conclusions can be obtained. Because of the assumption that the earth pressure distribution is inconsistent with the reality, the results calculated by the plane frame model recommended by code were different from the measured results.%因具有独特的优势,双排桩支护结构应用越来越广泛,但计算理论尚有待完善.结合软土地区的双排桩工程实例,对规范推荐模型与数值计算模型结果进行探讨并对比分析实测结果,表明由于土压力分配假设与实际不符,采用规范推荐的平面刚架模型计算结果与实测结果有一定差异.
