摘要
在文[1]的基础上,推导了所建立本构模型和渗流模型的三轴压缩情况下的方程,并给出了1个算例。结果表明,建立的本构模型能够反映微裂纹闭合摩擦滑移、微裂纹发生自相似扩展和微裂纹发生弯折扩展对变形的影响;建立的本构模型能够反映岩石剪胀特征;弯折微裂纹分支张开是使岩石渗流明显地增大原因。
The equations of the theories in previous paper are deduced for rock under triaxial compression.An example of presented models is gived. The example shows that the constitutive model can reflect the mechanical properties caused by the frictional sliding, mode- Ⅱ self-similar growth and kinking of closed microcracks under compression and swelling distortion caused by sheafing. The opening of partial microcrack during kinking makes seepage increasing.
