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.

Key words: grouting method, weterproofing agent, blasting, cavity, loess
