太平水库除险加固工程墙幕结合防渗设计

Seepage Control Design of Dam Diaphragm Wall Combined with Grout Curtain for Danger-removing and Consolidating Project of Taiping Reservoir

太平水库于1975年建成,已运行30多年,枢纽建筑物存在诸多问题,其中问题之一就是坝肩及坝基渗漏问题,已影响到水库经济效益及运行安全,为此采取了防渗墙与帷幕灌浆相结合的防渗处理措施以解决这一问题。文中介绍了水库的防渗设计,帷幕灌浆和防渗墙的施工工艺及质量控制。

The Taiping Reservoir had been completed in the year 1975,and its operation has lasted for 30-odd years.But there are many problems in building of hydroproject,one of which is seepage in dam shoulder and dam foundation.This problem has impacted the reservoir＇s economical benefit and operation safety.Therefore,a seepage control measure of dam diaphragm wall combined with grout curtain is adopted to solve this problem.In this paper,the reservoir＇s seepage control design,the construction techniques and the quality control measures of grout curtain and diaphrage wall are expounded.
