Gaining the maximum dry density of fill by compacting test 碾压试验确定回填料最大干密度
Maximum dry density 最大干密度
The research presents a correlative dry density method ( or xgm ) , which can calculate maximum dry density by field dry density 本文结合河南省交通厅1997年下达的豫交科( 9791003 ) “现场干密度推算最大干密度方法”课题开展硕士论文的研究工作。
At present , the maximum dry density , which is a very import parameter of the degree of compaction , is ascertained by standard indoor compaction test 目前,对于公路工程路基土施工质量压实度检测应用的最大干密度是通过室内标准击实试验来确定。
Considering that the way to gain standard maximum dry density value of xigeda filling is complex , this paper suggests adopt means combining field cbr test and compactness measuring to control construction quality 鉴于昔格达混合填料标准最大干密度取值的复杂性,建议采用现场承载比与压实度检测相结合的办法进行现场施工质量控制。
