摘要：Adopted with the actual value of statistic geo-stress, using RFPA software to simulate the hydraulic fracturing of underground. The sample is treated as elastomers and simplified into plane problem, submit strength, elastic modulus, Poisson ratio to weibull distribution. It could be found in figures that the size, length, extending direction of two crack is not identical. The cracks' forms grow into symmetry horizontal double-wing crack from the final result, besides, crack propagation direction is perpendicular to the direction of the minimum principal stress.
