Abstract
A system of vertical drains with combined vacuum and surcharge preloading is an effective 10 solution for promoting radial flow, accelerating consolidation. However, when a mixture of soil and
11 water is deposited at a low initial density, a significant amount of deformation or surface settlement 12 occurs. Therefore, it is necessary to introduce large strain theory, which has been widely used to manage
13 dredged disposal sites in one-dimensional theory, into radial consolidation theory. A governing equation 14 based on Gibson’s large strain theory and Barron’s free strain theory incorporating the radial and 15 vertical flows, the weight of the soil, variable hydraulic conductivity and compressibility during the 16 consolidation process is therefore presented.
