基于煤矸石的煤矿中转水池堤坝填筑试验研究
|
摘要
门克庆煤矿的中转水池堤坝填筑材料采用煤矸石和细砂。为了得到填筑材料压实后满足规范要求的相对密度,需通过堤坝填筑试验研究确定。试验分为室内土工试验和现场碾压试验,通过室内土工试验制定出了煤矸石含量P5、干密度ρd、相对密度Dr3个因素相关图;通过现场碾压试验,得到了煤矸石和细砂的在最优填筑比例下达到填筑标准的相关压实参数。以废弃材料煤矸石作为拟加固中转水池的堤坝主要填筑材料,既可以充分利用废弃资源,也可以减少煤矸石对环境的危害,具有很好的应用前景,将为类似工程提供借鉴。
The dam filling materials of transfer pool in Menkeqing coal mine uses coal gangue and fine sand. In order to get the relative density of meeting the specification requirements after the filling materials compaction, research should be determined by dam filling test. Test is divided into indoor geotechnical test and the field rolling test. Through the indoor test the author works out the content of coal gangue P5, dry density ρd, relative density-Drthree factors relevant figure, obtains the relative compaction parameters of coal gangue and fine sand with the filling standards under the optimum filling ratio through the field rolling test.Taking waste material coal gangue as the main filling materials to reinforce the transfer pool not only can make full use of waste resources, but also can reduce coal gangue harm to the environment, which have very good application prospect and provide reference for similar projects.
