...H. Fu; Z. Huang; J. Lin; J. Wang; J. Ni; Z. Gao; X. Zhu; X. Li Conventional vacuum preloading is widely used for dredged slurry treatment, but vacuum pressure loss often leads to inadequate bottom consolidation and uneven reinforcement. This study proposes a vacuum preloading method with top-bottom...

...L. Tang; J. Huang; Q. Liu; Y. Wang; X. Xiong The effectiveness of traditional vacuum preloading ( TVP ) for improving deep marine soft ground is fundamentally constrained by vacuum attenuation with depth and well resistance. To overcome these technical barriers, this study introduces a novel full...

...W. Geng; G. Xu; X. Li This study proposes a consolidation method combining expandable drainage systems – both synthetic and straw-woven – with intermittent vacuum preloading, addressing limitations inherent to conventional vacuum preloading techniques such as the formation of low-permeability soil...

...J. Sun; J. Li; P. Wang; L. Han; Q. Xue By integrating thermal energy into the reclamation process, the newly emerging thermo-promoted vacuum preloading ( TPVP ) can desirably enhance the dewatering efficiency for high-water-content slurry. Regrettably, barely no theoretical contributions...

...H. Lei; J. Li; S. Feng; Y. Bao; G. Zhang; S. Yu The conventional vacuum preloading method using prefabricated vertical drains (PVDs) suffers from vacuum pressure attenuation with depth. To address this limitation, this paper proposes a novel stacked PVD (S-PVD) vacuum preloading method...

...X. Lin; L. Shi; K. Yao; K. Wang; Y. Cai To improve consolidation pressure along the prefabricated vertical drain (PVD), the presented study introduced a novel technique, airlift-assisted vacuum preloading, which incorporated the concept of airlift into traditional vacuum preloading. The innovative...

... the theoretical model for the consolidation analysis of the vacuum preloading combined with short and long PVDs, the following assumptions are considered: 1) the soil is a saturated two-phase material including the incompressible soil particles and pore water; 2) the whole soil layer is composed of newly dredged...

...K. Yang; M. Lu; X. Geng; G. Wang Prefabricated horizontal drains (PHDs) combined with vacuum preloading (VP) presents distinct advantages over prefabricated vertical drains (PVDs) and has become a popular method for the treatment of dredged slurry. However, the effect of drains layout density...

...Q. Y. Dong; X. H. Ren; X. Y. Ge; P. Wang; H. Z. Liu Clogging near the prefabricated vertical drain filter during vacuum preloading reduces the efficiency of ground treatment, and existing research has yet to agree on the cause. This study conducted a small model test to comprehensively examine...

...H. Fu; Y. Cai; J. Wang; P. Wang Two representative laboratory tests, using vacuum preloading alone and vacuum preloading combined with variable-spacing electro-osmosis (EO), were performed on dredged marine clay slurry used for tideland reclamation. This combined method consists of the following...

... called ‘vacuum preloading combined with chemical conditioning’ is proposed to treat the disposed sludge. This study presents a case study of full-scale field implementation of the method in a sludge lagoon at the Changan landfill, China. In the first stage, the chemical conditioner was injected...
