摘　　要：针对深基坑抗承压水稳定性,分析了传统基坑抗承压水稳定性的缺陷。通过对基坑底隔水层抗承压水破坏机理和模式的分析,利用力学原理和三轴试验原理推导了对判断基坑抗承压水稳定性判别的简化公式。最后将成果应用到杭州庆春路过江隧道工程中。实践证明该方法是可靠的具有一定的应用价值。In the light of the deep foundation pit anti-bearing water stabilization,the article analyzes the defects of the traditional foundation pit anti-bearing water stabilization. Through the analysis of the anti-bearing water destroying mechanism and model of the water insulating course at the bottom of foundation pit,the mechanics principle and the three-axis experimental principle are used to deduce the simplified formula to judge the distinguishing of the foundation pit anti-bearing water stabilization. Finally,the result is applied in Hangzhou Qingchun Road Crossing-river Tunnel Project. The practice proves that this method is reliable and has some application value.
