In the process of deep and large foundation pit excavation in soft soil,the threat of high head confined water to foundation pit should not be underestimated.Starting from the direction of reducing confined water head,relying on the high pressure confined water head inrush accident of a deep foundation pit in soft soil of the north bank of the Yangtze River,the paper studies the engineering measures of reducing confined water head inside and outside the pit by decompression precipitation through numerical simulation calculation and comparative analysis of site monitoring data,so as to realize ...
