This post introduces the paper Analytical solution for one-dimensional chemo-hydro-mechanical coupled consolidation under time-dependent loading in buffer clay layer, published in the Canadian Geotechnical Journal (2025, 62: 1–13). Addressing the situation in landfills and similar works where the load is applied progressively over time, the study establishes a one-dimensional chemo-hydro-mechanical (CHM) coupled consolidation model for a buffer clay layer. The two coupled partial differential equations are decoupled by a linear combination, and analytical solutions are derived for four cases: ramp loading and exponential loading, each under single-sided and double-sided drainage. After verification against numerical solutions obtained with COMSOL Multiphysics, the influence of eight parameters on pore water pressure and contaminant transport is analysed systematically.
