某临海工程基底涌水涌砂影响因素分析

Affecting Factors Analysis on Basal Gushing Water and Sand for a Coastal Engineering

青岛为沿海城市,地下水水位高,给深基坑施工带来了许多困难。本文通过典型的临海工程实例,分析了影响基底涌水、涌砂的影响因素,利用有限元软件SEEP/W进行定量分析,计算得到各工况下发生涌水、涌砂临界厚度的数值,并提出有效建议。

For the coastal city of Qingdao,high underground water level brought many difficulties for deep foundation excavation construction. Through the typical coastal engineering example,this article analyzed the problem characteristics of gushing water and sand,and put forward some of the critical thickness of the gushing water and sand influencing factors. Quantitative analysis by finite element software SEEP / W was done. Finally it is concluded that the factors influencing the relationship with the critical thickness.
