摘要

通过分析群桩成桩后桩间土体固结的边界条件和初始条件，建立了饱和黏土中群桩桩间横观各向同性土体的空间轴对称固结问题的定解条件，应用数学物理方法求得该问题的级数解。通过土体固结与桩承载力的时效性之间的关系，利用承载力的实测资料换算得到的等效固结度，验证了解的合理性和适用性。同样，应用级数解求得的桩间土体的固结度可用于群桩基础的承载力的时效分析。

Abstract

The space axisymmetric consolidation model is established for transverse isotropy soil among Jacked-in Group-Piles. Then

series solution can be found by using methods of mathematical physics

considering the initial distribution and boundary condition of excess pore water pressure caused by setting piles. The comparison between the calculation values and the consolidation degree values which are deduced from the practical bearing capacity shows that the series solution obtained is reasonable. On the other hand

the consolidation degree results from the series solution can also be used for predicting the capacity of group piles.
