| 摘 要： | 深基坑降水,会增加土体的有效应力并使土体渗流固结。运用太沙基渗流固结原理,可以求得基坑降水后土体固结度Ut。通过土工试验过程的分析,推求得到了降水后基坑土体为任意固结度Ut时的c、φ值计算公式。结合工程算例,分析了深基坑降水过程中其土体c、φ值的动态变化特征。

| Abstract: | In the process of dewatering of deep excavation,effective stress of soil mass will be increased and seepage consolidation will occur in the soil mass.With Terzaghi's consolidation theory,the degree of consolidation U_t can be obtained after dewatering of deep excavation.Through analysis of the process of soil test,the calculation formula for values of c and φ of soil mass has been deduced when the consolidation U_t of soil mass is arbitrary values.With engineering calculation case,the dynamitic variation character for values of c and φ has been analyzed in the process of dewatering of deep excavation. |

| Keywords: | deep excavation dewatering values of c and φ |
