Stability Analysis on Surface layer of an Expansive Clay Slope with Consideration of Expansive Pressure

摘要：

　　Weathering effects,expansive pressure and pore water pressure are investigated to evaluate their effect on expansive clay slope stability.In particular,the effect of expansive pressure is analyzed to consider its effect on the stability of surface layer of the slope.In this paper,the distribution of expansive pressure in a slope is evaluated and used to analyze the stability of the surface layer of a clay slope.The proposed analysis method is applied in the third ring road project in Chengdu,China,where there are expansive clay slopes.Reasonable results are achieved.
