| Abstract: | A model testing system to form underground space and concrete support with synchronous blastenlargement method is set up. Model tests for 3 blastenlargement schemes and 5 ratios of concrete are carried out. The properties of soil in blastenlarging deformation and the thixotropic characteristics of concrete are analyzed. The optimum parameters and thixotropic time to build underground space and concrete support with synchronous blastenlargement method are given. |

| Keywords: | underground space model test blastenlarging deformation |
