详细信息

摘要: 针对环形支撑体系在基坑工程设计中存在的一些问题，从理论角度提出了优化设计的方法，并编制了相关的有限元程序。通过对程序计算结果的对比分析，筛选出较优的设计参数。以绍兴某个深基坑工程为例，详细计算分析了环形梁尺寸以及开挖顺序对基坑的受力和变形的影响。并将计算结果与监测资料对比，验证了本文方法的适用性，同时表明在某些特殊形状基坑中，环形支撑体系不失为一种有效支撑形式。

Abstract: Based on the theoretical analysis, a method to optimize the design of circular strut system in deep excavations is proposed. A FEM program based on the model is developed. By comparing the calculate results, some optimized design parameters are obtained. The proposed method is used to analyze a deep excavation in Shaoxing. The analytical results are compared with the measured data. It is indicated that the suggested method can be used to simulate the excavation process of similar excavations. The circular strut system is an effective way in some deep excavations with special space.
