| 摘 要： | 强夯加固近期粗粒填土时,夯点部位的土体明显产生了漏斗式塌陷,并且有数条环状和根状裂隙。针对这种特殊的地质特征,说明了由大孔隙到小孔隙,填土要经过瞬间的3个变化过程,而且在有效加固深度内土体呈“逆向转换”规律,同时分析了为什么夯点土体在成分均一的条件下,不同部位承载力悬殊这一关键性问题,对夯点间距的设计提供了理论依据。

| Abstract: | Obviously at the ramming point the soil produces a funneled subsidence and a number of ringlike and rhizomorphous crannies when the short-term big granular filling is rammed. The particular geological characteristic is proved that from big aperture to small aperture the soil goes through three changing processes in a twinkling. Thereby a law is deduced that in the effective depth the rammed soil obeys the "inverse transformation". At the same time the key question is analyzed and studied why at the different place the supporting force of the soil is the great disparity under equal composition. Thereby the theoretical basis is provided on the design for the distance between rammed points. |
