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.
