用室内试验方法研究了土体应力状态变化对其力学性质的影响。
The statistical relationship is proposed between mechanical properties of soils and the stress disturbance degree.
岩土体应力状态靠近极限状态线时,岩土体塑性剪切变形越来越大,趋于破坏;
The plastic deviatoric deformation becomes larger and larger and geomaterials tend towards to damage, when the stress state of geomaterials is close to the critical state line.
结果表明,在基坑开挖过程中,基坑壁附近的土体应力状态变化显著;锚杆锚固段应力呈非线性递减分布;
The result indicates that when the foundation pit is excavated, the soil stress state near the foundation pit wall changes obviously;
