泥砾开挖料极端级配填筑利用试验研究

Filling Test on Boulder Clay Excavated Materials with Extreme Gradation

围绕干密度、渗透、抗剪强度等3项关键指标,采用碾压体原位试验与室内试验相结合、敏感性试验与优化试验相衔接的方式,就邯邢渠段泥砾开挖料的极端级配进行系统工程应用研究,获取了作为坝壳料和防渗体材料的工程应用方法与相关特性指标,为其它级配的工程应用提供了参考基准。

It makes a study on systematic application of boulder clay excavated materials with extreme gradation in Handan canal section of Hebei Province by combination of in situ test with indoor test of roller compaction body,and conjunction of sensitive test with optimization test by concentration in three key indices of dry density,seepage and shear strength.In the test,the application method and features of dam shell and anti-seepage body material are obtained which provide a reference basis for projects with other gradation.
