水利工程下伏深层采空区处理方法

摘要

针对下伏采空区地面修建水利工程时地基难以处理的问题，以禹州矿区大型水利工程下伏深层采空区为例，介绍了采空区充填灌注方法，包括灌浆材料的选择、孔排距布置、灌浆压力的确定、阻塞方式、灌浆方法等，经过实践检验，效果较好。%For hydraulic projects with deep gob area beneath the ground , the foundation treatment is always difficult . This paper presents the grouting techniques to fill the gob area practically adopted in large scale hydraulic projects in Yuzhou mining area , including the selection of grouting materials , the drilling arrangement and distance of grouting holes, the grouting pressure, the blocking method, and the grouting scheme, etc.Practical examples show the effective-ness of the presented techniques .
