摘要
研制了围压条件下内压式岩石断裂韧性测试仪，并对试样进行围压下岩石断裂韧性的测试.结合实验数据，利用断裂力学理论求得了不同围压条件下的断裂韧性．解决了水力压裂设计所需要的断裂韧性这一重要参数的获取，有利于提高压裂设计、预测的精度．
Based on fracture mechanics theory, a device for measuring rock fracture toughness under confining pressure is developed, and the fracture toughness of 8 rock samples under different pressure is measured. A linear relationship between fracture toughness and confining pressure is found, which is important for hydraulic design and fracture prediction.
