【摘要】 本文重点介绍沛屯地区砂石垫层地基处理中,关于确定砂石材料最佳配合比的相关研究。根据当地实际情况,改良设计原有国内使用的堆积密度试验仪,进而利用堆积密度试验和击实试验,通过分组试验确定了砂石换垫层材料的最佳配比,并通过改变各组材料的含水量分析研究了含水率对密实度的影响。试验得出的结论不仅适用于沛屯地区,也可为今后同类型地区的软土地基处理提供参考依据。更多还原

【Abstract】 This paper studies on foundation treatment of sand-gravel cushion in Peitun.Firstly,the bulk density instrument which was ever used in the test was improved.Then,by doing the compaction test,the best rate of the material and the influence of moisture content by changing the rate of the material and the moisture content in different groups of the tests are known.The result of the test not only suits Peitun area,it will also provide the reference for the same type of soft foundation treatment in other districts.更多还原
