根据室内外水力致裂试验的结果，通过分析裂隙端都应力强度囚于的变化情况，研究了不同结构成分岩层阻抗水力致裂的能力，及岩性变化、交界面性质等对水力致裂裂隙扩展及承压水导升的影响。
According to the results of hydraulic fracturing test both inside and outside, by analyzing the changes of the stress intensity at the fracture end, the capability of hydraulic fracturing of rock with different structural components and the influence of lithology and interface properties on hydraulic fracturing Expansion and the impact of pressure water rise.
