【摘要】 在某水电站平硐勘探的基础上,应用地震波层析成像测试技术,对坝址区右岸平硐间测试,得到右岸不同岩体的波速分布。根据地震波速分布探明岩体地质构造和分布特征,确定岩体质量等级。平硐间地震波CT成果与地质构造资料的对比验证表明:硐间地震波CT具有良好的应用效果,为工程设计提供了可靠的地质资料。更多还原

【Abstract】 On the basis of the adits exploration of a hydropower station,the wave velocity distribution with the different rock mass can be obtained by seismic wave computerized tomography( CT) test technology on the right bank of the dam site. Through the seismic wave velocity distribution,the geological structure and distribution character of rock mass can be determined,and the rock mass quality grade can be ensured. Compared the result of seismic wave CT between adits with the geological structure information,the results show that the seismic wave CT between adits have a good effect,and it can provide reliable geological information for engineering design.更多还原
