三峡工程兴山峡口移民区滑坡防治与利用方案研究

Landslide Control and Utilization Program in Resettlement Area of Xiakou of the Three Gorges Project

摘要:

以三峡库区湖北省兴山县峡口镇移民迁建新址为例 ,研究了在滑坡防治工程的基础上 ,结合移民建设进行土地开发利用方案。在 1 80m和 2 30m高程采用 2排人工挖孔抗滑桩 ,有效地控制了滑体深层整体稳定性 ,并与上部公路建设相结合 ,形成了公路路面。在高程 2 0 0m和 2 60m一带 ,采用小口径钻孔灌注桩 ,穿过滑带 ,承重与阻滑相结合 ,根据建设规划随机布置 ,为建筑提供桩基础与平地的同时 ,增加滑体稳定性 ,形成了 4个平台 ,有效地解决了在滑坡体上安全开发土地的难题。

Abstract:

The utilization program of landslide mass is researched on the basis of landslide controlling engineering taking the resettlement site of Xiakou, Hubei as an example. Two rows of anti-sliding pile are distributing at the 180 m and 230 m altitude to effectively control the complete landslide, also provide the platform for highway and house construction. A lot of drilling piles with small diameter are installed depended on the house basement that provide well bear capacity, and can also resist sliding. Four platforms are constructed combined with landslide control, that solve the safety problem for developing land on the landslide mass.
