须家河组近水平软硬相间地层中斜坡破坏及处理对策

Slope Failure in Nearly Horizontal Soft and Hard Intercalated Strata of Xujiahe Formation and the Countermeasures

针对成自泸高速公路重点叙述了须家河组地层的地层特征,归纳了容易发生在须家河组近水平软硬相间地层中的斜坡破坏类型。在此基础上,分析破坏发生原因及其对工程的危害性和工程应对策略。通过工程实例具体说明在该类地质条件下进行地质选线和工程治理设计的原则。

With regard to Chengdu-Zigong-Luzhou Highway, this paper focused on the characteristics of Xujiahe Formation, and generalized the type of slope failure likely happened in the nearly horizontal soft and hard intercalated strata thereof, based on which the causes of failure, the hazards therefrom and the countermeasures were analyzed, then the principles of geological route selection and engineering control design were explained in details with project case.
