摘　　要：针对太原西北二环高速公路K18+620右侧高边坡出现的滑移现象及地质不稳定问题,通过现场勘查和地质调查,分析了高边坡岩体结构特征和边坡变形的主要诱发因素,利用简化Bishop法,进行了边坡稳定性计算和评估,计算结果表明,在天然、地震及有水工况下,边坡均存在不同程度的滑移风险,采用“锚杆+坡面格构”相结合的防护设计方案,结合排水系统设置和植被修复等综合防护措施,以提高边坡的抗滑能力及稳定性。Aiming at the slip phenomenon and geological instability of the high slope on the right side of K18+620 in Taiyuan Northwest Second Ring Expressway,this paper analyzes the structural characteristics of high slope rock mass and the main inducing factors of slope deformation through field investigation and geological survey.The slope stability is calculated and evaluated by using the simplified Bishop method.The calculation results show that there are different degrees of slip risk in the slope under natural,seismic and water conditions.The protection design scheme of"anchor rod+slope lattice"is adopted,combined with comprehensive protection measures such as drainage system setting and vegetation restoration,in order to improve the anti-sliding ability and stability of the slope.
