Abstract:According to the exponential flow law for soft clay and the constant coefficients of compressibility and permeability during consolidation, the equations and solution conditions of onedimensional large strain consolidation were established in Lagrangian coordinates with excess pore water pressure as variable. The computation module was solved by finite difference method to obtain the numerical solutions for pore water pressure. The numerical solutions of void ratio with different depth and settlement of foundation at certain time were solved, and the average consolidation degrees in terms of deformation and stress were both provided. The influence of exponent m on large strain consolidation behavior was analyzed by numerical examples. The difference of consolidation theory with exponential flow law between small strain and large strain was analyzed, and the condition that large strain must be considered in onedimensional consolidation of soft clay with exponential flow law was provided.
