滑坡是一种常见的地质灾害现象,对工程建设的危害很大,轻则影响施工,重则破坏建筑;由于滑坡,常使交通中断,影响公路的正常运输;大规模的滑坡,可以堵塞河道,摧毁公路,破坏厂矿,掩埋村庄,对山区建设和交通设施危害很大。长虹东大道K3+650—K3+820区段因路基切坡形成高边坡,施工过程中发生滑坡现象,造成边坡坍塌、坡脚挡土墙破坏、边沟变形、人行道上拱。本文根据现场岩土工程调查,认真分析了滑坡发生的主要原因,并对滑坡治理提出了合理化建议。
Landslide is a common phenomenon of geological disasters, which is very harmful to the construction of the project, from light construction to heavy construction and damage to the building. Landslides often interrupt traffic and affect the normal transportation of roads. Large-scale landslides can block the river , Destroying roads, destroying factories and mines, burying villages, and endangering the construction of mountainous areas and transportation facilities. Changhong East Avenue K3 + 650-K3 + 820 section due to the formation of high slope slope subgrade, the construction process of landslides occurred, resulting in the collapse of the slope, retaining the retaining wall of the slope foot, the ditch deformation, sidewalks arch. Based on the investigation of on-site geotechnical engineering, this paper carefully analyzes the main reasons for landslide occurrence and puts forward reasonable suggestions on landslide control.
