百色水利枢纽地下厂房区防渗与排水设计

Impervious and Drainage Design for Underground Powerhouse of Baise Project

针对本工程独特的水文地质条件 ,论述厂区洞室的渗控设计 ,采取在厂外设置一道排水孔幕并在其外侧设置防渗帷幕的渗控措施。经厂区渗流场计算分析 。

According to the hydrologic condition at damsite region of Baise project,the seepage control measure that set a system of drainage orifices at the outside of the powerhouse and an impervious curtain outside the drainage orifices are used. By analysing the seepage field calculation,the results shown that the seepage control measure is efficient.
