This airlift process can achieve nearly lossless transmission of vacuum pressure along the PVDs and induce pneumatic fractures that enhance soil permeability. In this study, a nonlinear consolidation model was developed with full consideration of the time-varying pressure condition and the permeability improvement associated with cyclic airlift operations. The analytical solution was obtained by employing the piecewise linearization technique, and was first verified by degenerating it into conventional vacuum preloading (CVP) process and comparing to the classical drain-well solution. The complete solution was further validated against large-scale model test data. Parametric analyses revealed that, compared with CVP, AAVP significantly accelerates the consolidation process, exhibiting not only faster pore pressure dissipation but also a greater magnitude of dissipation that exceeds the applied vacuum. Theoretical results indicate that the advantages of AAVP become more pronounced under greater treatment depths and in soil with adverse conditions such as smear and clogging effects, highlighting its strong potential for application in ultra-thick soft deposits and high-water-content reclamation land.</div></div>","PeriodicalId":55096,"journal":{"name":"Geotextiles and Geomembranes","volume":"54 3","pages":"Pages 430-442"},"PeriodicalIF":6.2,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146080572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, long-term settlement during the service period of infrastructure is often not adequately captured when soil structure degradation and creep are neglected. Existing models rarely consider the coupled effects of soil destructuration, creep, and nonlinear water flow in PVD-assisted consolidation. This study develops an axisymmetric finite-strain consolidation model incorporating an elastic–viscoplastic model with structuration (EVPS) based on the equivalent time concept. The formulation is applicable to clays possessing inherent structure that may undergo structure degradation under mechanical loading or PVD installation. The model considers soil creep, destructuration, smear effects, and nonlinear water flow, and is solved using an alternating direction implicit (ADI) finite-difference scheme. Finite-element comparisons are employed solely to verify the numerical implementation of the consolidation equations. Model performance is evaluated through comparisons with laboratory oedometer tests on natural structured clays and long-term field observations from the Haarajoki embankment. The results indicate that the proposed model can consistently reproduce pore-pressure dissipation and settlement evolution, including deformation occurring after primary consolidation over periods of several years to decades. Parametric studies reveal that soil destructuration, smear effect, and non-Darcian flow jointly govern the consolidation process. The proposed model enables more reliable prediction of consolidation behaviour in natural structured clays, which is essential for assessing long-term settlement and supporting rational design of ground improvement schedules.</div></div>","PeriodicalId":55096,"journal":{"name":"Geotextiles and Geomembranes","volume":"54 3","pages":"Pages 460-481"},"PeriodicalIF":6.2,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146190110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
