公路隧道穿越采空区注浆治理方法研究

Research on treatment method of grouting for highway tunneling passing through gob

在采空区上方修建高速公路时,由于采空区的稳定性得不到保证,常对高速公路建设造成重大影响,给设计与施工人员带来诸多不便。文章根据已有的注浆理论,对注浆材料进行了研究分析,并根据采空区特点提出合适的注浆工艺,运用多种检测手段综合评价注浆效果。

When highway is built above gob,the stability of gob can′t be guaranteed,therefore,it often has a significant impact on highway construction,which brings much inconvenience to the design and construction workers.According to the theory of grouting,the paper makes analysis and research on grouting materials,puts forward suitable grouting process according to the characteristics of gob,and comprehensively evaluates grouting effect with much detection means.
