摘要
将一种多裂纹相互作用的分析方法推广到类岩石材料的压剪裂纹相互作用分析中,并作为特例讨论了两共线压剪裂纹及两偏置平行压剪裂纹。结果表明:两压剪裂纹桥联区几何特征对其相互作用有决定性影响,该方法为进一步研究压剪裂纹的扩展和聚合提供了基础。
An approximate method of interaction of multiple cracks is extended to the study on interaction of frictional cracks in rock-like materials. The cases of two inclined collinear cracks and a pair of offset parallel cracks are discussed. The results show that interaction between cracks could produce either an enhancement or a shielding effect on the stress intensity factors depending on the positions of the cracks. The method can be used to study the mechanism of propagation and coalescence of cracks in rock-like materials.
