祁临高速公路灵石连接线李家沟滑坡原有支护构筑物因大雨发生部分损坏,为了防止滑坡破坏公路,针对损毁处进行了防护设计,论文以祁临高速公路灵石连接线李家沟滑坡为工程依托,采用Midas/gts建立相应计算模型,开展了锚杆挡墙的设计计算与施工要点分析,为今后类似工程提供参考。 In order to prevent the landslide from destroying the highway, the original protection structure of Lijiagou landslide was partially damaged due to heavy rain. The protection design was carried out for the damaged area. The paper takes Qilian Expressway Lingshi connecting line Lijiagou Landslide is based on the project, and the corresponding calculation model is established by Midas / gts. The design calculation and construction points analysis of anchor retaining wall are carried out, providing references for similar projects in the future.
