摘要
防渗帷幕灌浆是处理岩溶地区水库坝基坝肩渗漏的主要方法之一,它可以杜绝深、浅层的复杂的岩溶漏水问题,帷幕设计的合理性及其效果取决于水文地质、地下水的补排条件,水工建筑物结构之间的帷幕体的搭接形式,布置格局和边界范围。本文根据34处渗漏水库的灌浆实践,提出确定帷幕的深度和长度的原则,并得出了相关曲线和经验公式,对岩溶地区水库的渗漏处理进行探讨。
A principal way to the treatment preventing to seepage of dam foundation and dam abutment is seepage-preventing curtain grouting, which may prevent the complex rock leakage from the deep and shallow layers, curtain-designing feasibility and effects are determined by the recharge and drainage condition, the curtains involved with joint forms, arrangement patterns and boundary among the hydraulic structures. In accordance with the grouting practices at 32 sites of permeable dams, the principles of assuring the curtain depth and the curtain length are put forward, and the relative curve and formula are educed, the permeable treatments for the reservoirs in the karst areas are discussed.
