土基回弹模量与干容重关系分析

Analysis on the relationship between the modulus of resiliencefor earth subgrade and dry unit weight

通过对含水量对压实的影响分析,阐述了为什么现行路面设计方法是以回弹模量E作为土基的强度指标,但施工现场并不是直接用回弹模量E来控制土基压实程度,而是用干容重γ0

According to the analysis on the effect of water content on compaction, this article describes that the reason why the current method for pavement design is based on the modulus of resilience, E, as the strength index, while the modulus of resilience, E, is not used directly on site for controlling the compactness of earth subgrade and the dry unit weight is used to represent the level of compaction.
