摘要：The simulation experiment with similar material model is becoming more and more popular along with the underground engineering push to the depths gradually, coring directly in the scence has biggish difficulties. The fly ash and cement mortar were used as the simulation material, the mechanical properties of the similar material were studied by changing the ratio of aggregate to cementations material, the replacement ratio of fly ash to cement, the ratio of water to cementations material and the particle size of sand. By compare the failure mode and the stress-strain curve before the peak, the feasibility of similar material to simulate shaly sands were studied, and reasonable suggestions for improvement were given, which can provide valuable references for model test research.
