摘要
本文首先论述了基坑开挖过程中常用的降水方法———明沟排水和井点降水以及相应的水流运动。并简要阐述了动水压力分析法和管涌 (流砂 )的产生机理 ,推导出渗流力公式和管涌的安全系数 ,对影响基坑水力稳定的因素作简要评述 。
First of all,this article discusses the common precipition means in the couse of the opening group pit ——the clear channel drainage and the well dot precipition and the relevant current athletics.Then it briefly expatiates the move hydraulic pressure analytical method and the bring mechanism of canal gush,educes the seep force expressions and the safety factor of the canal gush,and brifly reviews to the infection factors of the steady to the group pit,educes the understand to the basic discipliantion of the ground water seep to the stability of the group pit.
