【摘要】 采用地震波法、钻孔声波法以及室内岩石力学试验法,对水布垭水电站面板坝趾板建基岩体进行了动、静参数测试,并根据所获的参数建立了岩体质量、岩体动力学和静力学参数三者之间的相关关系,对工程岩体进行了质量分级和质量评价。根据检测结果与分析,认为采用地震波法、钻孔声波法以及室内岩石力学试验综合评价水电站大坝趾板建基岩体工程质量是可行的,其成果可为大坝趾板建基岩体验收提供依据。更多还原

【Abstract】 Based on seismic wave method,borehole acoustic method and indoor rock mechanics test,the dynamic and static parameters of the foundation rock for the toe slab of the concrete face rockfill dam for Shuibuya Hydropower Station are tested,and then the relationship among the rock quality,dynamic parameter and static parameter are established with the parameters obtained from the test,furthermore,the classification and the quality evaluation are made as well.In accordance with the testing results and the analysis concerned,it is considered that the seismic wave method,borehole acoustic method and indoor rock mechanics test are feasible to evaluate the engineering quality of the foundation rock for the toe slab of the dam comprehensively,and the results can lay a reliable foundation for the accepting the foundation rock for the toe slab of the dam.更多还原
