碎石土压实性能试验研究
摘要:以现场取得的碎石土为原料,通过筛分试验确定其平均级配,以平均级配为基础,利用代替法设计试验级配。在试样含水量的确定上,结合碎石土的特点,以碎石土中细粒的多少来确定试样的含水量。通过等压制样的试验方法研究了含碎石(质量分数)、含水(质量分数)对碎石土压实性能的影响规律,并从理论上推导了最佳含石量的计算公式,通过理论与试验的对比分析,提出了确定碎石土最佳含水量和含石量的方法。
Abstract:With the in-situ gravel-rail as trial materials, mean gradation is determined by particle size analysis. On the basis of the mean gradation, test grading is designed with substitution method. According to the character of gravel-rail, the water content of samples is determined according to the content of clay. The laws of the compactibility with water content and gravel content are studled by the samples made under same vertical pressure. The formula of optimum gravel content is deduced from theory. With the analysis of theory and experiment, the methods of determining the optimum gravel content and optimum water content of gravel-rail are presented.
