削坡减载法在边坡稳定治理中应用
Application of Cutting Slope & Unloading Method to Slope Stability Treatment
【摘要】 边坡稳定治理方法有多种,结合具体边坡工程,利用极限平衡方法对该边坡在天然工况、开挖施工工况等7种工况下的稳定状况进行分析,该边坡在暴雨工况下安全系数不能满足稳定安全要求,考虑此边坡表层为深厚覆盖层,选用削坡处理方案对该边坡进行治理设计,校核边坡处理后的稳定状况,各工况下该边坡安全系数均满足要求.表明对该边坡采用削坡减载方式进行处理是可行的.
【Abstract】 Slope stability treatment has a variety of approaches.Combined with a specific slope engineering,and by using limit equilibrium method,the slope stability status in seven kinds of conditions such as natural condition,excavation construction condition,etc.,is analyzed.And the result shows that the safety factor in heavy rain condition can not meet the requirement of stability and safety;considering that the slope surface cover is a deep overburden,so the treatment scheme of cutting slope is chosen to deal with the slope.Finally,checking the slope stability situation after the treatment,it is shown that the safety factors under all the conditions meet the requirement;and the analysis results show that using the treatment scheme of cutting slope & unloading is feasible.
【Key words】 slope; stability calculation and analysis; cutting slope & unloading; limit equilibrium method;
