基坑围护结构承受的水压力计算理论的试验验证和分析

Test verification and analysis of calculation theory of water pressure on bracing construction of foundation pit

通过土体中水压力的传递试验和对水压力传递过程进行理论推导 ,证明了土体 (包括粘性土 )是可以传递水压力的 ,而且土体中的水压力均衡时间在工程意义上可以忽略不计 ,因此 ,在水土压力计算中 。

Experiments and theoretical derivation of water pressure transmission in soil presented in this paper show that the water pressure can be transmitted through soil and that the time of water pressure uniformization is so short (1-2 hours) that it can be ignored in engineering. Therefore, the effective stress theory of soil should be used in the calculation of soil_water pressure.
