Heat Transfer Characteristics and Loading Performance of Ground-Source Heat Pump System Pile

Energy is the material basis for human survival, economic development, and the social progress. With the growth of population and the improvement of per capita living standards in developing countries, energy becomes scarce. To improve the energy structure and seek sufficient stability in energy supplies has become issues of concern. Ground source heat just to meet the people's demand for energy, ground surface of shallow geothermal energy is a renewable energy stored. The ground source heat pump system pile are caring for two aspects: whether the pipes will influence the bearing capacity of the pile and whether the deformations of the pile will influence the buried pipes．In this paper, the bearing capacity influenced by the buried pipes is analyzed through the variation of the moment of inertia and the area of the pile．The results show that the buried pipes in the pile have little influence on the structures．
