| 摘 要： | 本文通过在软土地基深基坑支护中土压力、孔隙水压力的大量测试，经统计分析、反分析及对比分析，提出了主动土与被动土不同的受力机理，利用朗肯公式计算时，应取土的不同强度指标，即主动土压力计算取固结快剪指标，被动土压力计算取快剪指标。

| Abstract: | Through large amount of testings on earth pressure and pore water pressure on bracing of deep foundation pit of soft ground and based on various analyses the different mechanism of pressure on active earth and passive earth are proposed.Different strength indices of earth should be used when calculated with Rankine's formula.Consolidated quick shear index should be used when active earth pressure is calculated and quick shear index should be used when passive earth pressure is calculated. |
