掺钢渣稳定土的击实性能试验研究

为研究掺钢渣稳定土的击实性能,以焦桐高速公路工程叶舞段沿线低液限黏土为原材料,分析掺钢渣后影响其最大干密度与最优含水率的因素。在综合考虑钢渣掺量、钢渣陈化龄期和钢渣最大粒径3个因素作用下进行室内击实试验,利用正交试验法,得到了影响钢渣土干密度因素的主次程度,并通过极差分析法和方差分析法分析各个因素对击实土样最大干密度和最优含水率的影响规律。

Experimental Study on Compaction Performance of Stabilized Soil Mixed with Steel Slag

In order to research the compaction performance of the stabilized soil mixed with steel slag, the factors influencing its maximum dry density and optimum water content after mixing with steel slag are analyzed with the original material of low liquid limit clay along the line of Yexian-Wugang Section of Jiaozuo-Tongbai Highway Project. Carry out interior compaction test by comprehensively considering such three factors as mixing amount, aging period and maximum particle size of steel slag and get the primary and secondary degrees of the factors influencing the dry density of steel slag stabililized soil using orthogonal test method as well as analyze the influence rules of the factors to the maximum dry density and optimum water content of the compaction soil samples using the range analysis method and variance components method.
