英德市枫树坪水库地震勘探土坝渗漏
|
摘要
枫树坪水库土坝右岸是建在石灰岩地区，左岸是砂岩地区。右岸断层、溶洞、溶蚀、裂隙发育十分丰富。自建库后，土坝常常发生渗漏，并间有黄股状出本。对土坝右侧前后进行过３次灌浆处理，１９８９年底还采用土工股防渗处理，但直至现在效果并不十分理想。１９９５年年初．基本上又恢复到原来的渗漏水平。在此情况下，１９９５年８月采用ｓｔｒａＴａｖｉｅｗＲ１２地震仪对土坝进行了勘测。
Abstract: The right bank of the earth dam of Fengshuping reservoir lies in lime rock area, the left bank in sandstone area. Ever since the building of the earth dam,seepage often took place with intermittent yellow spray of water. Three times grouting was used to prevent seepage in the right side of the dam. At the end of 1989, geomembrane was also adopted to control seepage, but no satisfactory effect was gained. At the beginning of 1995,seepage was as serious as before. In this case .strata view R12 earthquake gauge was used to survey the earth dam in August, 1995.
