水库坝基综合地球物理勘察技术与应用

水库坝基地质条件关系到大坝建设质量，其前期的勘察工程至关重要。目前，利用物探与钻探工程相配合，可以获得坝基土岩介质较为丰富的勘察资料。结合地震折射波和并行电法对新建水库坝基进行勘察，确定了土层埋深、岩体风化带等特征参数，为坝基处理与施工提供可靠的依据。应用实践表明，利用综合物探方法可以提高对地质异常的判断能力，效果良好。

Integrated Geophysical Prospecting Technology of Reservoir Dam Foundation and Its Application

The geological conditions of dam foundation refer to the construction quality of dam for reservoir , and the early prospecting engineering is very important .At present , combining with geophysics and drilling engineer-ing, the rich exploring data of the soil and rocks in dam foundation can be gained .In the research the explora-tion of the new construction was done by the integrated method of refracted wave and parallel resistivity method . The characteristic parameters , such as the cover depth of soil , zone of weathering of rock , and so on , were con-firmed, and it can provide the reliable basis for the processing and construction of dam foundation .The testing results showed that the integrated geophysics method can improve the judging ability for the geological abnormali -ty in dam foundation , and it has good effect in the dam foundation prospecting .
