In this paper, a novel iterative coupling scheme is developed for solving coupled hydro-mechanical problems using reproducing kernel particle method. The numerical scheme calls the fluid and the solid solvers sequentially and iteratively until convergent solutions are obtained. To overcome the numerical instability problem, a simple stabilization technique is developed and proved to be uncondit...

One method to deal with the problem of soft soil is accelerate consolidation by preloading and prefabricating a vertical drain (PVD). Consolidation analysis was based on one-dimensional theory that required PVD as an equivalent circular well. Further studies simple approximate for consolidated were represented permeability coefficients, kve. The conductivity coefficient influenced coefficients....

Consolidation deformation induced by low frequency cyclic loads was investigated finite element analysis (FEA) and some available test data. Both one-dimensional (1D) consolidation the of a prefabricated vertical drain (PVD) unit cell were considered. With theoretical reasoning using results FEA, it has been established that amount rate continuous load with maximum increment q, can be calculate...

Abstract This paper presents a framework for modelling the random variation in permeability cement-admixed soil based on binder content and thereby relating coefficient of to unconfined compressive strength clay. The strength–permeability relationship was subsequently implemented finite element method (RFEM). effects spatial both clays RFEM is illustrated using two examples concerning one-dimen...

The paper presents classical and non-classical rheological schemes used to formulate constitutive models of the one-dimensional consolidation problem. authors paid special attention secondary effects in organic soils as well soil over-consolidation phenomenon. systems partial differential equations were formulated for every model solved numerically obtain settlement curves.
