阐述了合理选择填土含水量改善压实度的方法。
The method of choosing proper water content of fill to improve compaction degree is elaborated mainly.
填土的室内试验：填土含水量测定、颗粒分析和比重测定。
Laboratory fill test: fill water content, grain analysis and specific gravity test were tested.
得出干于最优含水量填土的抗拉强度高，极限变形也大，加荷速率对饱和土的抗拉强度没有什么影响。
The conclusions are as follows: When the Water content of filling soil is lower than the optimal one, the tensile strength is greater and the limiting deformation is larger.
