發(fā)布時間:2019-05-11 09:42
【摘要】:地質(zhì)雷達雖然應(yīng)用廣泛,對于水庫壩基的測試深度有待增加、測試可靠性有待進一步提高。利用水利部948項目資金從英國引進的格威系列地質(zhì)雷達,是目前國際上具有最低頻率的一款雷達,可以提高水庫壩基的探測深度和可靠性。通過大量的室內(nèi)模擬試驗,掌握了相關(guān)典型目標(biāo)物的格威地質(zhì)雷達圖像特征。通過大量的測試分析總結(jié),建立了深部逐步層次測試分析方法。南門峽水庫壩基的探測成果表明,在基巖中存在明顯的強滲漏帶,灌漿隧洞右岸局部地方明顯存在破碎帶,為水庫除險加固工程的設(shè)計和施工提供了技術(shù)支撐。
[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.
