| Abstract | A finite difference numerical code was written in MATLAB for the prediction of excess pore - pressures and settlements under cyclic loads. The numerical code was developed by approximating the Terzaghi’s 1D consolidation equation under time dependent loading using Crank Nicolson Finite difference scheme. The code considers the non - linear inelastic stress ~ strain relationship and can be used for both homogeneous and heterogeneous layers. The code was validated by comparing the results with those of analytical, experimental and field monitoring data available in the literature and a good agreement of the results shows that the code is well developed and can be used for the practical works. Results of the analyses show that both the maximum steady state degree of settlement and the maximum steady state average degree of consolidation decrease with decrease in time period and below a specific limit, both remain unchanged. Both also depend upon the percentage of loaded portion in a cycle. For a specific time period, with the increase in the percentage of loaded portion in a cycle, both increase. Besides, maximum steady state degree of settlement, for a specific time period, increases with increase in stress levels which is due to the non - linear stress ~ strain behavior |
