Temperature change affects the consolidation behavior of soft clay. An increase in temperature in soft clay leads to the dissipation of excess pore water pressure and the decrease of volume. This temperature-induced consolidation can be utilized as a novel approach to improve soft ground. In this study, in order to investigate the effect of heat injection through a vertical drain on soft ground consolidation, a test device was designed to install different-sized sand drains that enabled heat injection and temperature control of a vertical drain. Using the device, a series of consolidation tests was performed with varying heat injection and varying diameter of the vertical drain. During consolidation, vertical settlement and temperature at various locations in the ground were measured. After each consolidation test, the spatial distribution of void ratio in the ground was estimated. Test results showed that heat injection increased the radial temperature of the ground, and the increasing diameter of sand drain with an internal heat source also expanded the heating area in the ground. Furthermore, the larger diameter sand drain led to greater final settlement and lower void ratio.
