暴雨工况下老旧砌石挡墙滑坡变形特征与应急处置措施
摘要
Abstract
In recent years,there are geological hazards in Zhenjiang urban area every year in flood season.The occurrence time is concentrated after rainstorm,and the main danger is landslide.The proportion of landslide hazards caused by the collapse of retaining wall is greater than or equal to 50%.On July 11,2023,the fourth day after rain,the landslide on the west side of the fitness square in a community is a geological disaster caused by the collapse of the old masonry retaining wall under the influence of a typical rainstorm.This article summarizes the main influencing factors of this type of landslide risk through the study of its deformation characteristics,including geological lithology,terrain and topography,rainfall influence,and old masonry retaining walls.When the slope is supported by masonry retaining walls and landslide disasters occur,the retaining wall can be considered as a rock and soil mass with a certain shear strength for analysis.The obtained slope stability results are more in line with reality and have a certain degree of innovation.Targeted emergency response measures are proposed for this type of landslide,which has certain reference significance for similar geological hazard situations.关键词
