花岗岩崩岗侵蚀区坡面破坏及新型排水结构研究

Study on Slope Failure and New Drainage Structure in Granite Collapse-Eroded Area

文章通过总结花岗岩崩岗侵蚀区坡面破坏形式,分析了常见排水结构物的适宜性,并针对砌体结构边坡排水结构的破坏特征,研究了适宜的新型平台及急流槽排水结构。工程实践应用表明,新型排水结构能够很好解决花岗岩崩岗地区传统边坡排水结构物由于渗漏和堵塞引起的侵蚀和水毁破坏,与现有边坡排水结构相比,具有施工简便、成本低、工期短等显著优势,值得在相似边坡地质条件下推广和应用。

Trough summarizing the form of slope failure in granite collapse-eroded area,this article analyzed the suitability of common drainage structure,and studied the suitable new platform and chute drainage structure in view of the damage characteristics of slope drainage structure of masonry structure. The engineering practice application showed that the new drainage structure can well solve the erosion and water damage caused by the leakage and plugging of traditional slope drainage structure in granite collapse-eroded area.Compared with the existing slope drainage structure,it has the significant advantages such as simple construction,low cost and short construction period,thus it is worthy of promotion and application under similar geological conditions.
