<p>Many infrastructures have been built on unsaturated soft soil improved by vertical drains, and the soil ground maybe subjected to various waveform loadings. However, previous investigations into the radial consolidation behavior of unsaturated soil have neglected the well resistance in vertical drains under different waveforms of time-dependent loading. In this context, this paper aims to investigate the radial consolidation behavior of unsaturated soil with vertical drains under different waveforms of time-dependent loading, taking into account the well resistance. The governing equation for the radial consolidation of unsaturated soil based on Fredlund and Hasan’s consolidation theory are transformed into a set of equations by introducing two new variables, and the integration and the eigenfunction methods are applied to derive analytical solutions for radial consolidation of unsaturated soil considering well resistance are derived under equal-strain condition. Furthermore, the explicit analytical solutions are presented for different waveforms of time-dependent loading such as rectangular waveform loading, trapezoidal waveform loading, triangular waveform loading and haversine waveform loading. The proposed solutions are verified for accuracy through the comparison with the existing solutions, and the results are in very good agreement. Finally, the influences of various parameters including well resistance, the permeability coefficient ratio for air and water phases, and loading conditions on the radial consolidation of unsaturated soil with vertical drains under different waveform loading conditions are investigated. The proposed study can provide a theoretical basis for drainage materials application in unsaturated soil ground improvement projects by vertical drains for construction of infrastructures (i.e., railway or highway embankment, onshore large-scale storage facilities, bridges, etc.) under various waveforms of time-dependent loading conditions.</p>
