摘要
考虑夯击期间填土情况 ,引入极限孔隙比的概念 ,归并两类模型 ,建立了土体实际夯沉量计算公式及实用土方计算公式。提出强夯沉降换算系数 ,用以确定夯坑沉降与地面平均沉降间的关系 ,对极限孔隙比与沉降换算系数的意义进行了探讨。
In considering the conditions during compacting,conception of ultimate void ratio () is introdused.Two types of models are combined.The calculation formulce of the acfual compacted subsidence and the practical calculation formula of earthwork are established.The conirsion factor for compacted sabsidence (α) is proposed which is used to find out the relation between compacted subsidence and the average settlement of ground surface.In this paper,the meanings of and α are discussed.
