白石南河蓄洪灌溉工程土坝的质量控制

On Earth Dan's Quality Control in Baishi South River's Flood-impounding Irrigation Project

土坝工程施工中,筑坝土料是影响工程质量的根本因素,交城县白石南河蓄洪灌溉工程筑坝土料采于地表之下,土料组成复杂、分层多、含水量大,为保证工程质量,控制土料含水量就成为土料压实前的重点工作,控制铺土厚度和压实干容重也是质量控制的重要环节。

In the process of constructing earth dam,the earth material to construct earth dam is the basic factor that influences project＇s quality.For Baishi South River＇s Flood Impounding Irrigation Project,project＇s earth material is excavated underground,the composition of earth material is complex.it is located in many layers,and its moisture content is high.In order to ensure project＇s quality,controlling earth material＇s moisture content is the important work before compacting earth Besides,controlling the thickness of placing earth and controlling dry density of compacted earth are the important links to ensure quality too.
