| 摘 要： | 通过分析单桩成桩后桩周土体固结的边界条件和初始条件，建立了饱和黏土中单桩桩周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答。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，验证了解答的合理性和适用性。同样，应用级数解答求得的桩周土体的固结度可用于桩的承载力的时效分析。

| Abstract: | The two-dimensional consolidation in saturated soil around sunk pile is studied. Considered the initial distribution and boundary condition of excess pore water pressure caused by setting pile, the series solution can be found by using methods of mathematical physics. The comparison between the calculation values and the consolidation degree values which are deduced from the practical bearing capacity shows that the series solution is reasonable. On the other hand, the consolidation degree results from the series solution can also be used to predict the capacity of the pile. |
