Simulation and Experimental Studies on Similar Material of Rockmass

摘要

Model experimental basis is similar theory, that is similar to model and prototype, model can reflect situation of the prototype. Based on similar theory, adopting similar similar material of cement-gypsum to make model, its Brittle is close to rock, elastic modulus and compressive strength are adjusted greater regulation, and the technique is simple, the resource is abundant, the price is very low, so it is a good similar material. The effect of aggregate content, cement content, gypsum content and the consumption of water on the strength and elastic modulus of the similar material of cement-gypsum is mainly researched, its corresponding change rule and curve is attained, and the feasibility which simulate the rock performance by the similar material is proved by research. The ratio that some sedimentary rock are simulated by the similar material is put forward. A group of ratio which met the rock performance was got, this is a firm foundation for the further research mechanical property of rock masses which have fractal joints is established. These results provide useful references for rock mechanics simulation experiments.
