摘要
通过对某基坑不同开挖阶段的静力触探、标准贯入试验以及主、被动区土压力测试结果的分析，对土体力学特性在不同开挖阶段的变化进行了研究，得出了开挖卸载下土体的强度变化以及对主、被动区上压力的影响。
The variation of mechanical characteristics of soil during excavation is studied through the analysis of the results of Cone Penetration Test, Standard Penetration Test and the field earth pressure at different excavation stages. The variation of subgrade strength and its influence on soil pressure of active and passitive area due to the overlying unloading are deduced.
