摘要
由非均匀下挖导致支撑系统非对称变形的实测资料启示,研究分析软土深基坑不同的开挖顺序、支撑周边不同荷载分布的不同变形和受力特征,导出支撑设计的正常荷载和偶然工况的异常荷载及其荷载系数的取用.
On the basis of the unsymmetrical displacement data of the bracing system caused by the uneven excavating in soft foundation pit, the different sequences of excavating in soft foundation pit, the displacement and the stress features resulting from the load distributing round the bracing system are analyzed. The normal and abnormal load in occasional condition and the value of the load coefficient are determined.
