摘要
泸定水电站河床段覆盖层深厚,地质条件复杂,防渗墙设计深度最深段达110 m。整个施工过程采取了一系列新技术、新方法,包括泥浆固壁技术、接头孔技术、排渣管技术等,均达到国内领先水平。通过对施工成果的深入总结,初步形成了科学、具体、切实可行的深厚覆盖层防渗墙施工技术,可为类似工程提供参考和指导。
The overburden on the river channel in Luding Hydmpower Station is deep and the geological conditions are complex. The maximum depth of cut-off wall is designed up to 100 m. New technologies and methods for constructing the cut-off wall are adopted, including slurry-supported, hole-connector and spoil disposal technologies. They are advanced in China and consist of a scientific and practical construction system for cutoff wall in deep overburden. The construction of cut-off wall in Luding Dam is summarized herein and can be as references to similar projects.
