天生桥峡谷位于南盘江在贵州省安龙县与广西区隆林县接界处,长约26千米,国家项目的水电站就要建在这一峡谷河段上。库容和坝高规模巨大,称得上当今世界规模。为了开发利用天生桥峡谷河段的水力资源,五十年代后期就开始规划选点,后又不断加深勘测设计工作。通过详细工程地质勘察,对峡谷河段的岸坡变形特点、变形型式等有了了解,对滑坡发育条件、类型及其对水电工程建设的影响也有了进一步认识。
Tianshengqiao Canyon is located in Nanpanjiang in Anlong County, Guizhou Province and Guangxi Longlin County junction, about 26 km, the national project of the hydropower station will be built in this gorge reach. Large capacity and high dam dam, called the scale of today’s world. In order to exploit and utilize the hydraulic resources of the Tianshengqiao Gully reach, the planning and selection of sites began in the late 1950s, and the exploration and design work continued to be deepened. Through the detailed engineering geological survey, the deformation characteristics and deformation patterns of bank slope in gully reach are known, and the conditions, types of landslide development and their influence on the construction of hydropower project are also known.
