To analyse the thermal behavior of deep weak soil in this study, 4-meter length electric heating pipe was installed in field. It was made by Ni-Cr wire and consumed 1kw/m, which was designed to show 450℃ surface temperature. Also, it was installed at 3~7 m area below soil surface, three thermometer were installed at 5m depth to monitor the temperature variations. The results of in-site test were similar to line source model and program, the resulted graph showed log pattern curves. Therefore, the soil heating through pipe in ground could be used to soil improvement successfully. In addition, the vapor caused by soil |
