Efect of the ideal pvd and not ideal pvd in the simulation of a soft ground improved by vacuum preloading and PVD

Abstract

     This paper introduces the analysis of simulation methods of vacuum preloading combined with PVD to improve a soft ground. The simulation methods of ideal PVDs and not ideal PVDs were done with two actual projects. The obtained results of settlement, horizontal displacement, excess pore water pressure were compared with the actual monitoring results. Therefore, depending on the conditions of vacuum technology and experience of the contractor to determine how to simulate the drains to correctly estimate the final settlement as well as other behaviors of the ground.
