Follow in precursory relating documents, several equations of one dimension Large Strain Consolidation (LSC) and consolidation coefficients were discussed firstly. Based on this, a Finite Difference Method (FDM) equation was derived, which was the physical described LSC equation with variable displacement. Moreover, the initiate and boundary condition were dispersed by FDM, and the boundary of different layers of super soft soil was disposed of continuity. Finally,nonlinear group equations of LSC FDM solution was deduced for multi layers super soft ground by repeated method, and a FDM program of 1D nonlinear LSC analysis was compiled. Finally, a case showed a satisfied analysis result by LSCFDM.
