动力固结的理论与实践

动力固结的理论与实践 English Version

摘要: 土的动力固结（强夯法）是加固地基的一种方法。目前,国内外尚处于经验累积的阶段。本文首先介绍新设计及试制的土的动力固结仪以及试验的方法和成果。其次,根据室内试验的参数,用几种数值解法求解强夯后地基中的应力、孔隙水压力和变形,并与工地量测结果相校核。最后,在边界元计算的基础上,给出图表,供强夯加固地基的设计应用。

Abstract: Dynamic consolidation （heavy tamping） is one of recent methods for foundation, improvent. Up to the present time, this method still retains in experience accumula tion stage. This paper firstly introduces the new apparatus of dynamic coaolidation and its testing method and results. Secondly, by these laboratory parameters, stress, pore pressure and deformation in foundation after heavy tamping were obtained by three numerical methods. The calculated results were checked with those from field measurements. Finally, based on boundary element computation, a chart was plotted for design purpose of dynamic consolidation.
