Abstract

With reference to the special nature of the high liquid limit soil cutting slope in Shizhong Expressway,FLAC is used to analyze the preliminary stability of the slope.In terms of a certain gradient slope,the formula of relationships be- tween the slope height and the safety coefficient,and the critical height of the slope gradient are got,which offers a theoreti- cal basis to the assessment of slope stability.Slowdown slope and retaining wall are simulated to deal with the slope.The e- valuation on slope stability and the treatment efficiency are made,which offers a theoretical basis to the reasonable measures of treatment.
