Stability Analysis of Reticulated Soil Landslide Using on Deformation Zoning
The reticulated red soil is a widely distributed soil in the hilly area of central Hunan.The existence of the vertical mi-cro-cracks in the soil makes the surface water easy to infiltrate,and the dry-wet alternate environment accelerates the expansion and the shrinkage deformation of hydrophilic minerals,which has a significant impact on the stability of the slope.In the process of surveying a reticulated soil landslide,the slide body was divided into plane zones based on deformation signs.The slope stability was evaluated by the region so that the landslide survey can be more refined and the amount of engineering sup-port can be reduced.On the basis of the stability analysis of the existing sliding surface of the uniform soil landslide,the stabili-ty check of the deeply seated potential sliding surface of the slope can effectively avoid the failure of landslide control.Based on the simplified Bishop method,the stability analysis of a reticulated red clay landslide is performed.The slope is at the marginal-ly stable state,and heavy rainfall will induce the slope to produce a larger and deeply seated overall sliding.
