The Influence of Rainfall and Evaporization Wetting-Drying Cycles on the Slope Stability
نویسندگان
چکیده
The decay of soil strength and the change infiltration characteristics caused by dry wet cycle effect generated rainfall-evaporation process are important factors that induce slope instability. How to consider water-soil characteristic curve hysteresis on transient stability is key solve this problem. In paper, analysis slopes considering carried out based Geo-Studio. results study showed safety factor has an overall decreasing trend decreased 43% compared initial state. seepage dry-wet have certain regularity. location measurement points a greater influence magnitude pore pressure change: foot > middle top slope. Also, there significant response in with increasing depth at same location. rainfall intensity factor, but its not obvious when exceeds amount.

The Effect of Wetting-Drying Cycles and Plasticity Index on California Bearing Ratio of Lime Stabilized Clays
This paper aims to present an experimental and numerical study on the effect of wetting-drying cycles and plasticity index on the California Bearing Ratio (CBR) of lime stabilized clayey soils. The numerical analysis was carried out based on finite element method for comparison between results of experimental and numerical studies. Three clays with different plasticity indices were mixed with v...
