【摘要】：利用测井技术研究水电工程岩体结构和质量已被证明为一种可靠的方法。为评价卡里巴电站南岸扩机工程Sd01部位、进水口闸门井和进水口上游围堰岩体地质条件和结构特性,基于声学与光学测井技术开展了相关部位的现场试验研究,获得了上述部位的覆盖层厚度、基岩风化特征、基岩裂隙发育情况和基岩波速分布特性。试验结果表明:上述部位的水位分别为11.7,13.1,14.1~16.5 m;平均波速分别为3 200,3 500,2 000 m/s;覆盖层厚度分别为21,26,30 m;Sd01部位和闸门井岩体较完整,主要裂隙统计分别为12条和11条;上游围堰岩体较破碎,强风化。
[Abstract]:It has been proved to be a reliable method to study the rock mass structure and quality of hydropower engineering by using logging technology. In order to evaluate the geological conditions and structural characteristics of the Sd01 site of the south bank expander project, the intake gate well and the upstream cofferdam of the inlet of the Kariba Hydropower Station, the field tests of the relevant parts are carried out based on acoustic and optical logging techniques. The thickness of overburden, the weathering characteristics of bedrock, the development of bedrock fissure and the velocity distribution of bedrock wave are obtained. The results show that the water level of the above parts is 11.7g / 13.1 ~ 14.1g / L 16.5 m, the average wave velocity is 3 200 ~ 3 500 ~ 2 000 m / s, the thickness of the overburden is 21 ~ 2630 m / s, and the average wave velocity is 3 200 ~ 3 500 ~ 2 000 m / s, respectively. The Sd01 site and the Zhaomen well rock mass are relatively complete, the main fractures are 12 and 11, respectively, and the upstream cofferdam rock mass is relatively broken and weathered strongly.
