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。
Taking the relocation and relocation of Xikou Town, Xingshan County, Hubei Province, as an example, this paper studies the plan of land development and utilization based on the landslide prevention and control project combined with the resettlement construction. Two rows of manual digging anti-slide piles were adopted at 1 80m and 2 30m elevations to effectively control the overall stability of the sliding body and combine with the construction of the upper part of the highway to form the road surface. At the elevation of 200m and 260m, small-diameter bored piles are used. Through the sliding belt, the combination of load-bearing and slip-resistance combined with random layout according to the construction plan will provide the pile foundation and ground for the construction and increase the stability of the slide body Formed 4 platforms, which effectively solved the problem of safely developing land on the landslide body.
