岩石压剪断裂判据及其应用

Compress Shear Fracture Criterion of Rock and It's Application

摘要: 本文介绍了大理岩等脆性材料单边切口试件的压剪断裂试验情况。结果表明,压剪断裂判据可以用表示。文中列举了该判据在对坝踵水平裂缝等问题分析中的应用。

Abstract: In this papar compressive shear fracture tests for brittle specimens (such as marble, etc.) with an edge crack are described. The test results indieate that compressive shear fracture criterion may be expressed as λ12K1Ⅰ + |KⅡ| =KⅡc, As an application of this criterion, analysis of horizontal cracks at the heel of a dam is also presented.
