1引言下坂地水利枢纽工程坝基深厚覆盖层垂直防渗处理在国内均无先例,深度超过了现行规范适用范围,技术上难度大,在极为复杂地质结构层上筑成了150 m的垂直防渗墙(上墙下幕),在应对施工条件复杂高
1 Introduction The vertical seepage control treatment of the dam foundation deep underburden of Xiabantian Water Conservancy Project is without precedent in China. The depth exceeds the applicable scope of the current code and is technically difficult. The vertical seepage control of 150 m on the extremely complicated geological structure layer Wall (wall curtain), in response to the construction of complex high
