The typical problem that occurs when the conventional vacuum preloading (CVP) method is applied to dredged soil is that the drainage is impeded, permeability is progressively reduced, and clogging occurs in prefabricated horizontal drains (PHDs). This paper proposes a method in which air booster through PHDs under vacuum preloading to reinforce newly dredged soil, and thereby solve the clogging problem. To evaluate the proposed method, several experiments were conducted using soils with variable degrees of consolidation and the effect on clogging determined. Furthermore, the proposed method was compared to the CVP method considering several variables monitored during consolidation and after consolidation. The results indicate that the proposed method is superior to the CVP as it more effectively alleviates the clogging problem. These findings could provide design criteria for dredged soil consolidation in similar projects and for scientific research and engineering practice.

常规真空预压（CVP）方法应用于疏浚土壤时出现的典型问题是排水不畅，渗透性逐渐降低，预制水平排水管（PHD）发生堵塞。本文提出了一种在真空预压下通过PHDs空气增压器加固新挖出的土壤，从而解决堵塞问题的方法。为了评估所提出的方法，使用具有不同固结度的土壤进行了几次实验，并确定了对堵塞的影响。此外，考虑到在固结期间和固结后监测的几个变量，将所提出的方法与 CVP 方法进行了比较。结果表明，所提出的方法优于 CVP，因为它更有效地缓解了堵塞问题。
