三峡工程移民迁建区地质环境复杂 ,建设用地严重不足。如何在治理的基础上对滑坡等灾害地质体开发利用是一项风险极大 ,但具非常现实意义的课题。本文论述了预应力锚拉桩在库区大型滑坡防治中的应用成果 ,这种方法不仅能有效地控制滑坡体的稳定性 ,同时 ,也能根据移民工程要求提供适宜的建设用地 ;介绍了注浆方法对库区分布较广的以崩塌、滑坡、岩溶成因为主的崩滑堆积体的改造问题 ,它不仅可以大大降低移民迁建区地基与边坡处理的工程造价 ,也为库区灾害地质体的改造提供了范例 ;弃渣是库区极为突出的环境地质问题 ,不仅危害长江 ,也对移民迁建区构成严重威胁 ,本文介绍了巫山新城等利用加筋土技术处理弃渣 ,并大大增加建设用地的实例 ,由于该挡墙高达 5 6 m,超出了一般意义下的加筋土挡墙范畴 (通常不超过 2 0 m) ,因此出现了前缘筋带断裂和面板脱落问题 ,本文介绍了应用锚管注浆技术进行面板修复的设计 ,为复杂地质条件地区高加筋挡土墙的安全修建提供了经验
Three Gorges Project resettlement relocation complex geological environment, construction of a serious shortage of land. How to develop and utilize landslides and other geological disasters on the basis of governance is a very risky subject with very practical significance. This paper discusses the application of prestressed anchor piles in the prevention and control of large landslides in the reservoir area. This method can not only effectively control the stability of landslide bodies, but also provide suitable land for construction according to the requirements of resettlement projects. It is not only able to greatly reduce the project cost of foundation and slope treatment in relocating the resettlement area, but also for the disaster of the reservoir area The reconstruction of the geological body provides an example. Waste slag is an extremely prominent environmental and geological problem in the reservoir area. It not only endangers the Yangtze River but also poses a serious threat to the relocation area. This paper introduces the Wushan New City, This greatly increases the number of sites for construction. Since the retaining wall is as high as 56 m, it exceeds the range of reinforced earth retaining walls (usually not more than 20 m) in the general sense. As a result, This paper introduces the design of panel repairing using the grouting technology of the anchor pipe and provides the experience for the safe construction of the highly reinforced retaining wall in the complex geological conditions
