Thermomechanical Behavior of Soil: Energy Extraction through Pile Foundation

能源需求不断增加，化石燃料储备不断减少，人们对碳排放的有害影响更加关注，因此有必要寻找替代、可再生和清洁的能源。地热能是一种清洁和可再生能源，可以通过桩基（能源桩）经济地提取。据估计，在住宅和商业建筑中使用地热能可减少45-80%的二氧化碳排放量，并节省18-56%的成本。通过能源桩提取地热能在加拿大是非常可行的，特别是在冬季，因为地球表面以下几英尺的温度保持稳定在20°-35 ° C的狭窄范围内。

Increasing energy demands, dwindling fossil fuel reserves and a heightened concern for the detrimental effects of carbon emissions have made it necessary to search for alternate, renewable and clean energy sources. Geothermal energy is a form of clean and renewable energy that can be extracted economically through pile foundations (energy piles). It is estimated that the use of geothermal energy in residential and commercial buildings may lead to 45-80% reduction in CO2 emissions and to 18-56% cost savings. The extraction of geothermal energy through energy piles is very viable in Canada, particularly during the winter months, because the temperature at a few feet below the earth's surface remains stable within a narrow range of 20°-35°C.
