Abstract

In order to improve the analytical precision of strength of sandstone with three intermittent fractures, a method for analyzing the strength of sandstone with three intermittent fractures based on discrete fracture model as an approximation is proposed. Firstly, the distribution model of horizontal stress sandstone gas with three intermittent fractures and the analytical model of strength of sandstone with three intermittent fractures based on fluid mechanics and discrete fracture model as an approximation are provided; secondly, the uniaxial and triaxial sandstones are tested to obtain the relation of uniaxial compression strength and velocity of longitudinal wave; finally, the advantage of algorithm performance is verified through experiment.
