反倾向层状岩质边坡失稳模式及支护对策

Failure Models and Supporting Measures of Antidip Sandwich Rock Slope

在对反倾向层状边坡进行地质调查研究基础上,提出了4种反倾向岩质边坡失稳模式,并就其破坏机制和稳定性分析方法进行讨论,根据不同失稳模式的反向坡情况,采用相应的支护措施。水是诱发反向坡边坡失稳的重要因素,设计中应合理布置排水措施。

Based on the geological investigation for many antidip sandwich rock slopes,four types of failure models with respect to the antidip rock slope are presented here.Furthermore,the analytical methods for the stability and failure mechanism of slopes are studied.The slope reinforcement measures in advance should be adopted according to the failure models of antidip slopes.Water is the important factor for the failure of antidip rock slopes,so the issue to ensure drainage must be considered in the slope design.
