滑带土体强度恢复过程中基质吸力变化分析
Analysis of changes in matric suction during the strength recovery process of sliding zone soil
摘要
Abstract
The riverbank soil will exhibit the self-healing phenomenon of the sliding surface under the influence of wetting after a landslide.In order to investigate the self-healing behavior of soils and its influence mechanism on the strength properties of soils,this paper explore the influence of matrix suction on strength recovery of soils,based on repeated shear experiments and filter paper method experiments.By analyzing the changes in strength recovery,matric suction and time,the influence of matrix suction on strength recovery is explored.An empirical formula for the value of effective stress parameters of the slope under critical conditions is obtained.The research results have great guiding significance for the value determination of soil strength parameters in landslide areas.关键词
