泰斯公式在软土地区管井降水中的应用

Theis Formula's Application of Lowering Water by Tube Wellin the Soft-land Area

在软土地区,深基坑工程施工过程中经常会遇到地下水,由于地下水的存在,给正常施工带来许多问题。这时,必须降低地下水位。运用地下水动力学的有关原理,从工程实际出发,阐述了工程降水的基本理论和方法,诠释了泰斯公式在软土地区管井降水工程中的应用条件和环境,并应用于工程实际,运用泰斯公式预测管井降水时地下水水位降深的方法有效性较强,收到了较好的效果。

In the soft -land area, we usually meet the groundwater during our project construction. Due to groundwater, it bring into many problem for natural construction. At this time, the groundwater level should be lowered. The article applies the relevant principle of groundwater dynamic, and with considering the fact of the engineering, describes the basic theory and method of lowering Water for engineering, annotates application condition and environment of Theis formula in lowering water by tube well in the soft-land area. In practice, Theis formula is applied to forecast the lowering water by tube well is more effective than the method of descending groundwater level and gets better effect.
