土体的压实能耗和合理压实度要求

推导了土体在压实过程所需施加的能量,分别在线性和非线性条件下给出了土体压实能耗的表达式,并进行了具体的计算分析和比较。分析结果以及一些计算数据表明在高密阶段,土体的进一步压实将引起能耗的急剧增加,因此,对提高压实度的要求一定要慎重.并认为如何确定一个合理的压实度要求,还需要做大量的试验研究.

Energy consumption and proper requirement for soil compaction

The energy consumption of the soil compacting process is analyzed. Two expressions of energy consumption under linear and nonlinear conditions are presented respectively. With these expressions, detailed calculation and comparison are carried out. The analytical results and calculation data show that further compacting of high-density soil will lead to radically increase of energy consumption, so we shall be prudent when increasing the requirement of compaction amount. The authors suggest that a great deal of research and experiment is still needed in order to define a proper requirement for the amount of soil compaction.
