摘　　要：在山区、丘陵区,开发建设项目挖方量大。经理论分析,临时堆放的挖方,在坡度β<土壤内摩擦角ф和无暴雨、大风的情况下,能处于稳定的状态;弃渣场必须修建挡渣墙,挡渣墙的稳定性涉及到抗滑、抗倾覆和抗塌陷三个方面,满足该三方面的稳定性要求,挡渣墙才能达到稳定状态。In the mountain area, hilly area, the construction project excavation develops greatly. Through theory analyzing piling up excavation temporarily,if slope β〈inner frictional angle Ф,under the situation of no strong wind and storm,it can be in the steady state;abandoned dreg field must build retaining wall whose stability includes anti-sliding,anti-overturning and anti-collapsing. Meet the demands of this three respects,the retaining wall may reach the stable state.
