Abstract:

Pore-water in saturated soil gains both way drainages in radial directions by installing annular sand-layered drainages into the soft soil ground, and then the excess pore-water pressure can be dissipated along the two lateral surfaces of every annular soil layer. As addition of radial dissipation surface and reduction of dissipating distance, soft soil foundation can consolidate faster. Based on these ideas, the corresponding mathematical model of saturated soil consolidation and its analytical solution is presented; and then by a case study, the distribution and development of excess pore-water pressure, and consolidation characteristics of saturated soil are analyzed.

Key words: excess pore-water pressure, drainage way, annular soil layer, consolidation, mathematical model
