“柱状节理玄武岩工程特性研究”项目2013年底通过中国水电工程顾问集团有限公司验收。会议验收认为,该项研究解决了白鹤滩水电站设计重大关键技术难题,经济效益显著,具有推广应用价值。该项目由华东勘测设计研究院承担,依托白鹤滩水电站工程。对柱状节理玄武岩工程特性进行了全面系统的研究.成果已应用于白鹤滩水电站工程的可行性研究和招标设计中。项目主要研究成果:①系统研究了坝区柱状节理玄武岩的空间分布、基本特征、柱状节理的成因,进行了柱状节理分类。首次提出了“柱状镶嵌结构”岩体结构类型,提出了适合于 “Research on Columnar Joint Basalt Engineering Properties ” project was accepted by China Hydropower Engineering Consultants Group Co., Ltd. at the end of 2013. Meeting acceptance that the study to solve the Baihetan Hydropower Station major key technology design problems, significant economic benefits, with the promotion and application of value. This project is undertaken by East China Survey and Design Institute and relies on Baihetan Hydropower Station Project. A systematic and systematic study on the structural characteristics of columnar jointed basalt has been carried out.The results have been applied in the feasibility study and bidding design of Baihetan Hydropower Station Project. The main research results of the project: (1) The spatial distribution and basic characteristics of columnar jointed basalt in dam area were systematically studied, and the causes of columnar jointed joints were studied. For the first time proposed “columnar mosaic structure ” rock type of structure, proposed suitable
