淤堵效应是疏浚淤泥真空预压处理中普遍存在的现象。同时考虑淤堵效应沿深度的衰减以及淤堵区内渗透系数沿径向的变化，基于Hansbo固结理论建立了考虑淤堵效应的疏浚淤泥真空预压固结解析解。通过与已有解的对比验证了本文解的合理性，并通过参数分析的方式研究了淤堵效应以及疏浚淤泥性质对真空预压固结情况的影响。结果表明：淤堵效应对疏浚淤泥真空预压固结速度影响显著，随着淤堵区最大半径、淤堵区衰减系数及淤堵系数的增大，固结速度逐渐减小；随着疏浚淤泥非淤堵区渗透系数的增大，固结速度显著提升，而随着疏浚淤泥体积压缩系数的增大，固结速度则减小；竖向排水板（prefabricated vertical drain, PVD）影响半径越小，固结速度越快，但达到一定阈值后，继续减小竖向排水板的间距对固结速度的提升效果有限。

The clogging effect is a prevalent phenomenon in the vacuum preloading treatment of dredged slurry. Both the depth-wise attenuation of the clogging effect and the radial variation of soil permeability within the clogging zone were considered. On this basis, an analytical solution for the vacuum preloading consolidation of dredged slurry was developed based on Hansbo's consolidation theory. Comparisons with other solutions were conducted to verify the reliability of the proposed solution. The influence of the clogging effect and the properties of dredged slurry on vacuum preloading consolidation was studied through parametric analysis. The findings reveal that the consolidation rate of vacuum preloading of dredged slurry is significantly influenced by clogging effect. As the maximum radius of the clogging zone, the attenuation coefficient of the clogging zone, and the clogging coefficient increase, the consolidation rate gradually decreases. An increase in permeability coefficient of dredged slurry in non-clogging zone markedly enhances the consolidation rate, while an increase in the volume compression coefficient produces the opposite effect. A smaller influence radius of PVD leads to a faster consolidation rate. However, beyond a certain threshold, further reductions in the spacing of PVDs have limited impact on improving the consolidation rate.
