摘要
介绍了京沪高速公路化临段工程桥涵台背回填砂砾料的质量标准和砂砾料最大干密度试验方法 ,对试验中的一些问题提出了处理意见 ;分析了砂砾级配、粗细程度、含泥量对回填质量的影响 ;
Quality standard and test method of maximum dry density of grit filler are introduced for bridge & culvert retailing backwall refilling of Hua-lin sect project of Jing-hu high.The treatment idea for some special problems confronted in the test is presented.The influence of grit gradation,coarseness and contents of mud on refilling quality is analysed.The feasibility of several compactness test methods frequently used for checking grit compactness is discussed.
