缓倾角层状边坡变形破坏机制及整治措施

以国道108线广(元)南段公路缓倾角层状边坡的变形和失稳破坏为典型结构，在滑坡区岩体结构、水文地质条件、岩体水力学特征、滑坡形态特征和滑坡运动学特征等综合分析基础上，重点讨论了滑坡变形破坏的模式及产生的主要控制因素，并对滑坡进行了稳定性综合评价。在此基础上，对不同整治措施的技术可行性及经济指标进行比较分析，提出了经济、合理、有效的整治方案。

A Study on Mechanism and Countermeasures of Deformation and Failure of Stratified Side Slops with Gently Inclined Bedding

Deformation and sliding failure of stratified side slops with gently inclined bedding have occurred in Guang-Nan section of No.108 national highways during the construction period. On the basis of comprehensive analyses of structure of rock mass, hydro-geological condition and rock mass hydraulic property of slide district,and landslide shape and its kinematics character ,the models of the mechanism of deformation and failure and main induced factors are mainly discussed in this paper. Consequently, stability calculation and synthesis valuation of the landslides are performed.Last,technique feasibility and economic target of landslide control measures are compared and an economic rational countermeasure is put for ward.
