摘要
龙口海域软岩巷道在围岩应力达到峰值后,围岩破坏加剧、变形迅速增加,呈现出强烈的流变特性,本文针对这种现象,在典型地层选取岩样,使用岩石流变扰动效应三轴实验仪进行流变实验,并根据流变测试结果对流变曲线进行了拟合分析。
After peak stress in surrounding rock of soft rock roadways in Long Kou sea area,the damage of surrounding rock is severe,the deformation increasing rapidly,showing a strong rheological properties. This paper is based on this phenomenon,selecting sample in a typical formation,using rheological instrument with triaxial and perturbation loading devices for rheological experiment,according to the rheological test results fitting and analysising the rheological curve.
