考虑轴平移技术系统误差的边坡稳定性分析
Slope stability analysis considering systematic error of axial translation technique
摘要
Abstract
In order to analyze the stability of unsaturated soil slope,we investigate the influence of saturation on permeability coefficient.We establish the relationship between the soil water characteristic curve (SWCC) and the unsaturated soil strength under the consideration of the permeability coefficient and matric suction.Using Abaqus finite element simulation software,we compare the SWCC measured by axial translation technique and modified calculation method,and analyze pore water pressure,the slope position,slope deformation,and the plastic zone of the slope.The results show that the direct analysis of slope stability by SWCC with axial translation technique will give smaller slope deformation and smaller equivalent plastic zone than those of the real situation,and the real strength will be exaggerated.So there exists a security problem.The application of SWCC with correction calculation method can better grasp the real situation in the slope soil and reduce the engineering hidden trouble.关键词
