摘要:
采用自主研发的离散元软件MatDEM,依据能源管桩的现场热响应试验,提出了能源桩离散元数值模拟的建模方法,对能源管桩的热响应试验过程进行了模拟研究,得到了桩周土体的位移分布,桩芯和桩周土体的温度分布,通过与现场实测数据的对比,验证了利用离散元法研究能源桩换热性能的有效性,该方法在研究能源桩与土体的热-力学行为特征方面具有广阔的应用前景。
Abstract:
MatDEM, a self-developed discrete element method software, was used to simulate the thermal response test(TRT)of energy PHC pile. The modeling method was proposed based on a field test. The distribution of X directional displacement in soil around the pile was obtained. The temperature transfer process between soil and the pile was investigated. By comparing with the measured temperature in the field, the effectiveness of the discrete element method in simulating the heat transfer process of energy piles was verified. This method has broad application prospects in studying the thermo-mechanical behavior of energy piles and soils.
