摘要
通过用空心厚壁带径向对称裂纹的方柱形试件进行液体压裂来测定岩盐的断裂韧度，探讨了围压。
Thick-walled cuboid specimen with axial symmetry notchs are used to measure rock salt fracture toughness with hydraulic fracturing method.The effects of comfining pressure,axial pressure and length of crack on the fracture toughness are also studied experimentally in this paper.
