小断面硐室中大型充填溶洞防渗治理技术

Anti-seepage Treatment Technology for Large-scale Filling Caverns in Small Section Diverticulum

在各类工程,特别是岩溶地区水利水电工程中,需要对地下大型溶洞进行一定程度的治理,以保证建筑物能发挥设计功用。本文根据某水利枢纽工程帷幕工程所完成的工程实例,对小断面硐室中大型充填溶洞的开挖和防渗处理技术进行分析总结,为类似工程的设计、施工提供参考。

In all kinds of projects,especially in water conservancy and hydropower projects in karst areas,it is necessary to carry out a certain degree of treatment on large underground caves to ensure that the buildings can play their design functions.According to the engineering example completed by the curtain project of a water conservancy project,this paper analyzes and summarizes the excavation and anti-seepage treatment technology of large-filled caves in small-section diverticulum,and provides reference for the design and construction of similar projects.
