【摘要】 工程区岩土体的工程地质性质研究历来是水利水电工程中研究的重点。坝区岩土体的工程地质性质在很大程度上决定了水电工程的造价和成本,对水工建筑物的安全施工和运营有着重要的影响。针对工程区岩土体工程地质性质的研究,不论是在丰富和发展理论知识上,还是在解决具体工程问题上都具有重要的意义。本学位论文以拟建纳子峡水电站为依托工程,研究了坝区岩土体的主要工程地质性质。 首先从工程区的区域地质背景入手,系统研究了该区地质构造、地层岩性、地震活动特征及褶皱断层的发育情况等,确定了该区岩土体赋存的地质环境。其次,系统分析和研究了该区岩土体的特征及成因机制,同时利用物探、钻探等手段,对岩土体进行了现场测试和分析。通过测得数据及相关理论知识,对岩土体的动力学特性和渗透特性等进行了深入研究。在此基础上,综合考虑该区岩(土)体的各种工程地质性质,对其进行了科学合理的分级和质量评价。 研究结果直接服务于生产实践,为该水电站的施工和建设提供重要的技术理论支持。更多还原

【Abstract】 Study on the engineering geology property of the rock-mass and soil-body is always the keystone in the water and electricity field. The properties of the rock-mass and soil-body in the dam area decide the price and cost of the project and have got the important influence to the safe construction of the hydraulic structures. Research that aim at the engineering area rock-mass and soil-body not only enrich and develop the speculative knowledge ,but also have the important meaning in resolving concretely engineering problems. With the support of the Nazi Gorge water power station which is going to be built, the graduate paper studies the main engineering geology properties of the rock-mass and soil-body in the dam area.Firstly, commence from the regional geology background of the engineering area, the paper systematically studies the geological structure, strata and lithology, earthquake movable characteristic and drapes and faults etc, and then analyzes the geological background of the rock-mass and soil-body in this area. Secondly, the paper summarizes and analyzes the rock-mass and soil-body’s characters and the causes of formation. At the same time, the methods of geophysical prospecting and drilling are used to test and analyze the characters in the locale. Optimizing all kings of data and referring to the relative theories, the paper emphatically studies the dynamic response and permeability of the rock-mass and soil-body in this area. Based on all above researches, the author analyzes and synthesizes all kinds of the engineering geology characters, and then, carrys on the classification and quality evaluation to the rock-mass and soil-body in the dam district.All research results serve the productive practice directly, and provide the important technique theories for the construction and building of the hydropower station.更多还原
