砂砾石土料的压实特性

以某机场砂砾石填料的击实试验和碾压检测结果为基础，分别讨论了典型砂砾石料的颗粒特性，砂砾石料粗粒含量对最大干密度和最佳含水量的影响，以及不同含水率不同碾压方法对砂砾石土料压实特性的影响。并运用多项式拟合法最大干密度与粗粒料含量，最佳含水率与粗粒料含量和压实率与含水率的相关方程，从而可以通过一定量的击实检测试验，利用相关方程计算出各片，层土体的压实性指标后，再对其进行合理快速的检测。

Compactibility of Grit

On the basis of an airdrome grit fillings'compaction tests and rolling inspection, the classic grit granulation, the influence of the coarse grain content upon the maximum dry density and the optimum water content, the effect of the different rolled-on methods upon the compactibility of grit are systematically discussed. Dependent equations between the maximum dry density and the coarse grain content, the optimum water content and the coarse grain content, the degree of compaction and the water content are produced by the polynomial fitting method. Therefore, with these equations produced by some compacting tests and the calculated data, the grit inspections of different parts and layers can be carried out reasonably and quickly.
