根据对低液限粉质路基土在不同击实功作用下所得击实试验数据的分析,论述“经济击实功”的存在,并对指导路基压实有现实意义。通过计算,分析击实功的提高引起上述有关物理指标的变化规律,强调饱和度在击实及压实中的重要意义。同时针对低液限粉性土击实试验,总结了低液限粉性土的击实特性,击实干密度与含水量、击实功的变化规律及相关关系,并通过试验数据得出了三者之间的回归方程。
Based on the analysis of compaction test data of low liquid limit silty soils with different compaction results, the paper discusses the existence of “economic compulsion” and has practical significance in guiding the compaction of subgrade. Through the calculation and analysis of the improvement of compaction achievement, the above-mentioned changes of physical indices are emphasized, and the importance of saturation in compaction and compaction is emphasized. At the same time, according to the experiment of low liquid limit soil compaction, the compaction characteristics, solid density and moisture content compaction, compaction and compaction of low liquid limit silt soil were summarized, The regression equation between people.
