摘要
提出了岩芯饼裂主要受地应力平均值控制的观点,说明了岩饼表面圆周状对称拉裂坎以及垂直拉裂坎方向擦痕的形成原因,结合工程地质讨论了岩体的弹性模量和内聚力。
This paper bring forward the viewpoint that geostress average value controls the destroy of discal drill core. Explain that the tension fracture is mainly fracture formal at periphery of drill core and the cause of formarion of crack bank and slickenside of symmetry within the rock core. At last, the elastic modulus and cohesion of rock mass related engeneering geological characters are disscussed.
