【摘要】：二郎山1号滑坡位于龙胆溪左岸,滑坡前缘采用了坡脚挡墙防冲刷工程,10 a之后位于龙胆溪凹岸部分坡脚挡墙破坏。针对坡脚挡墙破坏形成的原因,对比分析了目前常用冲刷防护结构的局限性,提出了采用台坎式挡墙新组合结构进行修复,组合结构主要由挡土墙、墙底抗滑键、墙脚台坎以及耐磨肋组成。介绍了组合结构设计计算方法,并通过造价分析说明台坎式挡墙结构与其它防冲刷相比在经济上具有明显优越性,可为其它同类地质灾害防治提供参考。
[Abstract]:Erlangshan No. 1 landslide is located on the left bank of Gentianxi. The slope foot retaining wall is used in the front edge of the landslide. After 10 years, the slope foot retaining wall is damaged in the concave bank of Gentianxi. In view of the causes of the failure of the slope foot retaining wall, the limitations of the commonly used scour protection structure are compared and analyzed, and the new composite structure of the platform bar retaining wall is put forward. The composite structure is mainly composed of the retaining wall and the anti-slide key at the bottom of the wall. The base of the wall and the wear-resistant rib. The design and calculation method of composite structure is introduced, and the cost analysis shows that the platform bar retaining wall structure has obvious economic superiority compared with other scour prevention and control structures, which can provide reference for other similar geological hazards prevention and control.
