“引汉济渭”工程移民安置点的地质灾害及防治措施

在南水北调工程推进的同时,为解缺水之患,陕西省力推“引汉济渭”工程,即通过黄金峡水库、黄金峡泵站、黄三隧洞、三河口水库及穿越秦岭山脉的超长隧洞——秦岭隧洞等,将水量充沛的长江一级支流汉江水调入严重缺水的黄河一级支流渭河水系.黄金峡水库和三河口水库的建设将淹没部分库区的村庄,库区移民安置点的选择将成为工程建设的头等大事.分析在移民安置点选址规划过程中,地质灾害对移民安置点的威胁及其防治措施.

Geological Hazard of the Resettlement Spot in the Hanjiang River to Weihe River Water Diversion Project and Its Preventive Measure

When the South-to-North Water Diversion project is been promoted,Shaanxi province are also pushing for the Hanjiang river to Weihe river water diversion project to solute the water shortage risk,namely through the gold gorge reservoir,the gold gorge pumping station,the Huangsan tunnel,the three estuaries reservoir and the long length Qinling tunnel which passes hrough the Qinling Mountains,the water of the Hanjiang River which is a branch river of the Yangtse River is been transferred into the Weihe river which is a branch river of the Yellow River.Some villages were swamped because of the construction of the gold gorge reservoir and the three estuaries reservoir.The site selection for the resettlement spot in reservoir area becomes the major event in the project construction.The immigrants’ reception work is carried out well is not only benefit to the project construction,but also benefit to the social stability.The site selection and planning process of the resettlement spot is analyzed,the threat of geological hazard to the spot and its preventive measure are analyzed also in the paper.
