By changing initial moisture content, compaction density and overlying load, a series of indoor loaded swelling ex- periments were carried out on Nanning expansive soils, and the time - history characteristics as well as its variation law of loaded swelling under different initial conditions were obtained. Further based on Sigmoid＇s excitation function, a swelling time - history model that considers the coupling effects of initial water content, compaction density and overlying load was established, and the relevant model parameters were deter...
