三峡水库岸沿岸移民区地质灾害防治研究

STUDY ON PREVENTION AND TREATMENT OF GEOLOGIC HAZARDS IN RESIDENTS RELOCATING AREA ALONG THE COAST OF THREE-GORGES RESERVOIR

长江三峡水利工程是举世无双的宏伟工程 ,其水库的百万移民大都采取就地后靠安置 ,水库沿岸地质条件较复杂 ,滑坡、崩塌众多 ,地质灾害对移民的安全有重大影响 ,国家对三峡水库沿岸移民区的地质灾害防治给予高度重视 ,在几十年长期勘察研究的基础上 ,拨资进行现阶段的大规模地质灾害防治。防治工作有重大的社会、经济效益和较高的科学技术难度。本文分段论述了库区地质灾害特征以及以往防治研究历史 。

In the Three-Gorges Reservoir area on Changjiang River, million people are mostly relocating from the previous sites backward to new sites, where geological conditions are complex, landslides and collapses were frequent. Thus, the geologic hazards could affect the safety of residents. Our government has paid great attention to the prevention and treatment of the geologic hazards in the reservoir area. After investigation and study for decades, at present stage an investment is made for large-scale prevention and treatment of geologic hazards. This paper deals with the characteristics of geologic hazards in the reservoir area, previous history of their prevention and controlling, the main issues in study at present stage and the main problems to be further studied.
