摘要

碎石桩复合地基在工程上的应用非常广泛

其应力应变性状的研究已很深入

固结问题也得到了不同程度的研究

但已有的解析式大多较复杂

工程中难以应用。将桩间土径向整体作为一个研究对象

从而避开单独考虑因施工造成的涂抹作用的影响

根据排水量与体变等效原理

用平均超孔隙水压力的概念推导出碎石桩加固双层地基简化的固结计算式。由该方法可直接得到碎石桩和桩间土不同深度的平均超孔隙水压力和平均固结度

也可计算复合地基整体固结度。所推得的解析式简洁

且实用性强。

Abstract

Gravel-pile composite foundation has been applied widely to reinforce actual engineering; and the characteristics of its stress and strain have been studied deeply. The consolidation of the reinforced foundation has been researched to a certain extent

but the known analytic formulas are mostly complicated

so they are difficult to be used in engineering. Radial soil around pile is considered as a whole element in this paper

the effect of the coating caused by construction is not necessary to be considered. According to the theory of equivalent of seepage discharge to volume change

a simplified formula for consolidation of double-layered ground reinforced by gravel-piles is derived from the concept of average excess pore water pressure. This method can solve the average excess pore water pressure and average percent consolidation of the gravel pile and its surrounding soil

and the average percent consolidation of the entire reinforced foundation can be also obtained. This formula is laconic and has the advantage of application.
