格威系列地质雷达及其在水库坝基渗漏探测中的应用
发布时间:2019-05-11 09:42
【摘要】:地质雷达虽然应用广泛,对于水库坝基的测试深度有待增加、测试可靠性有待进一步提高。利用水利部948项目资金从英国引进的格威系列地质雷达,是目前国际上具有最低频率的一款雷达,可以提高水库坝基的探测深度和可靠性。通过大量的室内模拟试验,掌握了相关典型目标物的格威地质雷达图像特征。通过大量的测试分析总结,建立了深部逐步层次测试分析方法。南门峡水库坝基的探测成果表明,在基岩中存在明显的强渗漏带,灌浆隧洞右岸局部地方明显存在破碎带,为水库除险加固工程的设计和施工提供了技术支撑。
[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.
