Finite element analysis of soft ground improvement by vacuum preloading combined with surcharge preloading

Using the powerful parametric features of Pro/E modeling for the assembly of the track board, and building up Three-dimensional solid modeling. Finite element analysis with the simulation of mechanical motion to simulate the track through the soft ground of the forest were carried out. It can significantly reduce the design costs and speed up the development cycle to adapt of the requirements of the modern forestry industry.

In this paper, a soil-water coupled finite element analysis incorporated the macro-element method is carried out to investigate the effect of variable permeability coefficient on the consolidation of the ultra-soft ground using vacuum preloading. Sys cam-clay model is employed as the constitutive model of the ultra-soft soils. When the drain space becomes from 60cm to 40cm, there is significant acceleration in the numerical settlement of the ground using the constant permeability coefficient, which is quite different from the observational results. When the variable permeability coefficient where a liner relationship between the void and the logarithmic value of permeability coefficient is adopted is employed, there is a good accordance between the numerical and observational settlements. According to the distribution of variation in the void, the largest variation in the void occurs at the top several layers and therefore the predominant settlement can be attributed to the volumetric compression of the top several layers.
