摘要

根据埋深为6～13 m的某浅埋人防隧洞的前期稳定性分析，提出了对该人防隧洞选取灌浆加固处理方法。在工程的具体实施中，进行了两种浆液的配比实验，并分别确定了该人防隧洞在积水段和无积水段的加固材料及其配比。依据工程实际制定了灌浆施工工序，确立了浆液扩散半径以及3套灌浆终止条件。由灌浆扩散半径及岩芯强度测试的工程灌浆效果检验得知，此次加固措施完全达到了预期的效果和目的。

Abstract

According to the stability analysis of one shallow-buried air-raid shelter of which buried-depth is about 6m to 13 m

a grouting strengthening method for the air-raid shelter is proposed. During the construction

the mixture ratio experiments of two kinds of mortars are made. According to the mixture ratio

it is determined the strengthening materials and their mixture ratio of seepage area and no-seepage area; and according to the real construction

it is determined the grouting process

the spread-radius of the mortars and three kinds terminating-plan of the grouting. It can be concluded that this strengthening measures attain the expecting effects and purposes

according to the testing effect of the spread-radius of the mortars and the compressive strength of drill cores.
