雅中换流站大件运输道路小关沟段滑坡特征及治理措施分析

Analysis on Landslide Characteristics in Xiaoguangou Section for Large-scale Equipment Transportation of Yazhong Converter Station and its Control Measures

摘要:

道路堵塞点的临时整治对确保大件运输道路的通畅性和安全性，甚至是对确保雅中~江西±800千伏特高压直流输电工程如期投运至关重要。本文以雅中换流站大件运输道路小关沟段滑塌整治为例，介绍并分析了该滑坡体总体状况及病害现状，结合大件运输要求对比各设计方案在滑坡体处治效果、施工周期等方面的优缺点，确定了滑坡最终的临时整治方案，以期为同类工程提供参考。

Abstract:

The temporary renovation of road blocking points is very important to ensure the road accessibility and safety for large-scale equipment transportation, and even to ensure the scheduled operation of Yazhong-Jiangxi ± 800kV HVDC project. Taking the landslide renovation in Xiaoguangou section of large-scale equipment transportation road of Yazhong converter station for example, the overall situation and disease statue of the landslide mass are introduced and analyzed, and the advantages and disadvantages of each design scheme in landslide renovation effect, construction period, etc., are compared according to the requirements of large-scale equipment transportation. And finally, the final temporary renovation scheme for landslide is determined, which can provide a reference for the similar projects.
