摘要 针对山西太古公路发生的路基整体滑塌灾害,根据公路原有横断面、滑坡后的地表形态及已揭露的位于公路内侧的滑移面,参考滑带室内试验强度参数的标准值及工程经验和《滑坡防治工程勘查规范》,通过专业的边坡稳定性分析软件SLOPE/W,采用极限平衡法对滑带强度参数进行了反演分析,合理且可靠地确定了路基内侧滑移面的强度参数,为该滑坡后续的治理方案提供可靠的技术支持,也为同类工程滑带强度参数的选取提供一个思路。 Aiming at the subgrade overall slump disasters happened to Taigu Highway in Shanxi Province, according to existing surface configuration of cross - section and landslide and revealed slip surface located at inner side of highway, referencing to standard value and engineering experience of laboratory test strength parameters of landslide slip zone and " Landslide Control Engineering Exploration Specifications", by using professional slope stability analysis software SLOPE/W, adopting limit equilibrium method, inverse analysis has been implemented on landslide slip strength parameters and reasonable strength parameters of subgrade inner side sliding surface has been determined, which not only provids reliable technical support for subsequent treatment solutions for the landslide but also provides a idea for selection of strength parameters for similar engineering projects.
