摘要
我国经济高速发展极大地带动了西部水电工程资源的开发,在水电工程建设中,枢纽区岩体质量等级的评价是工程建设的基础,系统、准确评价坝址区岩体质量等级对工程建设具有指导意义。首先采用地震层析成像法、单孔声波法、钻孔变模法等物探方法的测试结果,对锦屏一级水电站坝基岩体质量等级进行定性和定量分析研究,并建立其相互关系;再运用钻孔全景图像成果验证了岩体分级的合理性。研究成果表明,综合物探方法可定性和定量评价水电站岩体质量等级,对类似工程具有可借鉴性。
The hydropower resources have been improved with the development of China's economy in western China.In the process of hydropower project construction,it is very important to evaluate the rock mass quality in the dam site.The systematic and accurate evaluation of rock mass quality in the dam site area is then of great significance to guide the construction of the project and ensure the quality of the project.The qualitative and quantitative study on the rock mass quality of the dam foundation of Jinping hydropower station is carried out by using the methods of seismic tomography,single hole acoustic wave and borehole variable mode,and establishment of their relationship.We verify the rationality of rock mass classification using borehole panoramic image.The research results show that the integrated geophysical exploration can be used to evaluate the rock mass quality of hydropower station,and it can be used for reference in similar projects.
