摘　　要：以秦岭山区某高速公路特大桥侧斜坡的稳定性和治理方案为例,通过现场调查、地质钻探等研究手段,分析影响斜坡稳定性的成因及主要因素,论证斜坡的稳定性。根据坡体及公路构筑物的特征,提出综合治理方案,该斜坡治理完成已三年,整体处于稳定状态,加固治理方案取得了良好的效果。Based on the stability and treatment scheme of side slope of an expressway extra-large bridge in Qinling mountain area,the causes and main factors affecting the slope stability are analyzed by means of field investigation and geological drilling,and the stability of the slope is demonstrated.According to the characteristics of slope and highway structures,the comprehensive treatment scheme is put forward.The slope has been treated for three years,and the whole slope is in a stable state,and the reinforcement treatment scheme has achieved good results.
