Considering the material nonlinearity and the one-dimensional consolidation problem in which the initial effective stress varies along depth, the analytical solution is difficult to obtain because of the complexity of its solution. The general solution is obtained by numerical methods. The author established a semi-analytical method to solve the nonlinear one-dimensional consolidation problem of soft clay along the depth of initial effective stress, compiled the calculation program, and obtained detailed pore pressure and settlement curves through detailed calculation, and then through analysis and comparison, The nonlinear one-dimensional consolidation properties of soft clay foundations are discussed.
