格威系列地質(zhì)雷達(dá)及其在水庫(kù)壩基滲漏探測(cè)中的應(yīng)用
[Abstract]:Although the geological radar is widely used, the test depth of reservoir dam foundation needs to be increased, and the test reliability needs to be further improved. Gwey series geological radar, introduced from Britain by the Ministry of Water Resources 948 project, is a radar with the lowest frequency in the world at present, which can improve the detection depth and reliability of reservoir dam foundation. Through a large number of indoor simulation experiments, the image characteristics of Gwyre ground penetrating radar (GPR) of related typical targets are mastered. Through a large number of test analysis and summary, the deep step-by-step hierarchical test and analysis method is established. The detection results of the dam foundation of Nanmenxia Reservoir show that there is an obvious strong leakage zone in the bedrock and a broken zone in the right bank of the grouting tunnel, which provides technical support for the design and construction of the reservoir reinforcement project.
