The purpose of this article is to provide the new way and feasible technical parameters for the development and utilization of Bentonite resources and the Permeable Reactive Barrier engineering practice.

目的 为膨润土资源的开发利用和PRB的工程实践提供新的途径和可行的技术参数。

The binomial deliverability equation can only be used to describe the high velocity non-Darcy filtering flow. For low permeability fracturing gas wells, due to low permeable property and high flow conductivity of the formation, the filtering flow laws of the formation are different from those before fracturing, and binomial deliverability equation can not be used for the flow condition of gas wells, therefore, new equation is needed.

二项式产能方程只能描述高速非达西渗流，对于低渗压裂气井，地层的低渗透性和裂缝的高导流能力使得其渗流规律已经和压裂前大不一样，二项式产能方程已无法描述气井的生产状况，必须建立新的方程。

At many case of bank foundation, such as the case of upper strongness and lower weakness, strong permeable foundation of dyke, strong permeable foundation of dyke containing low penetrability soft intercalation and the dyke foundation by alternation of low and strong penetrability layer, the appropriate condition of various upright seepage prevention measure (whole cut-off wall, half cut-off wall and hanging cut-off wall) and the optimization of seepage prevention measure are analyzed.

从渗流基本理论出发，以压力水头为基本未知量推导多孔介质三维饱和—非饱和、稳定—非稳定渗流问题的微分方程以及方程的有限元格式；在饱和非饱和渗流场的有限元分析中，不仅考虑了饱和区的水体渗流情况，而且也考虑了非饱和区的水分运动情况，将饱和渗流场与非饱和渗流场统一起来进行研究，整个渗流场采用一个支配方程。
