The Effect of Thermal Cyclic Induced Consolidation in Bangkok Soft Clay from the Usage of Energy Pile

Abstract

The innovation of Energy pile for use in Green Building Trend was introduced to be the simple basic concept of using the pile as the heat exchanger to dissipated the heat from the air conditioning system to the soil mass and water around the pile itself. In the Bangkok area where the thick soft clay was present. Due to the cyclic order of heating and cooling of the temperature and the decreasing of the water’s viscosity. This study will mainly focus on the behavior of the consolidation in Soft Bangkok Clay which induced from Thermal cyclic that causing creep in soil structure in the long term by using the modified Oedometer that equipped with the controlled temperature water circulation system. By using the configuration that the temperature is at 30 degree Celsius in the cooling loop and 40 degree Celsius in the heating loop for temperature setup criteria for 100 loops. The consolidation will be performed with the assumption that the in-situ stress is at 65 kPa with OCR = 1.3. Other than that, the Included the presence of Thermal Conductivity from Thermal Response Test from Full-scale Model from Test site which contains 3 types of piles that are 30 cm diameter concrete spun pile at the depth of 9 meters, 14 and 16.5 cm diameter Micro Steel pile at the depth of 16 meters and the last, 15 cm diameter Screw pile at the depth of 13.5 meter
