In order to improve the explosive resistance ability of underground space,this paper uses the outer intercross bolted rock to reinfore the underground space structure,then the test model was built and he explosive resistance of mass structure was studied by model test,according to the data from explosive model test,outer intercross bolted rock mass structure is effective reduction on underground space relative displacement by 20 ~ 50 percent,and reduction acceleration by 20 percent,under the same explosive load. The model test results demonstrate that intercross bolted rock mass structure can enhance explosive resistance ability.
