| 摘 要： | 针对爆扩成腔稳定性差、渗水率高及遇水坍塌等问题，采用注浆抽浆法对爆炸空腔进行了支护，并进行防渗小型实验研究。确定了注浆临界水灰比为0.8:1，分别对重力注浆、压力注浆以及压力注浆加防水剂和无支护的4个空腔进行了支护对比实验。实验表明：重力注浆不足以达到要求，压力注浆是一种解决支护和防渗较为可行的方法，加入防水剂后效果更好。

| Abstract: | Grouting method was used for shoring and preventing seepage in blasted cavity soils,in order to solve the blasted cavity soils question of stability of stability and seepage rate and collapse.Comparison tests of the gravity grouting method,pressure grouting method, the pressure grouting method method with the waterproofing agent and without any support were done by using the critical water-cement ratio of 0.8:1.It is proved that the gravity grouting method can not meet the need;the pressure grouting method is feasible for shoring and preventing seepage in blasted cavity soils;and it is better with the watrproofing agent added. |
