"The stress fissure" was demonstrated in the lateral column of the greater compression. and this reflected the mechanically anchoring effect.
压迫较重者,侧索内出现应力性裂隙,反映了机械性锚固效应的作用。
Based on the creep curves of soft rock under uniaxial compression, a damage variable and a hardening function are introduced into creep model to express the nonlinear creep behavior of soft rock. A new nonlinear model for axial and lateral creep is established for soft rock.
根据对单轴压缩条件下软岩蠕变特性的分析,引入损伤变量和硬化函数,建立软岩轴向和横向非线性蠕变模型。
For samples at three-axial compression test, its failure forms include friction slippage, self-analogue plane expands and crankle expands of micro-cracks when the lateral stress is tensile stress or smaller value.
对于三轴压缩的岩石试件,当侧向应力为拉应力或很小时,其破坏形式主要是微裂纹的摩擦滑移、自相似平面扩展和弯折扩展。
