水利枢纽工程溶塌角砾岩隧洞涌水塌方施工技术

Construction Technology of Water Gushing and Collapse in Collapsing Breccia Tunnel of Water Conservancy Project

对溶塌性角砾岩特性地貌岩溶发育特点进行综合分析后发现,使用普通的处理方法很难实现对塌方体的高效处理,因此,出台了自进式管棚处理办法,使塌方体得以高效处理。论文针对水利枢纽工程溶塌性角砾岩隧洞涌水塌方的初期支护和施工工序等情况开展了全面而透彻的分析,实现了人们从涌水塌方段的安全通过。

After a comprehensive analysis of the characteristics of karst development of collapsing breccia geomorphology,it is found that it is difficult to achieve efficient treatment of landslides by using ordinary treatment methods,so a self-entering pipe shed treatment method is introduced to make efficient treatment of landslides.A comprehensive and thorough analysis is carried out on the initial support and construction procedures of the collapse breccia tunnel in water conservancy project,and the safe passage through the collapse section is realized.
