摘要 针对渠道冻胀数值模拟分析依赖于实测温度而无法直接预测渠道冻胀及设计的缺陷,考虑日照对衬砌渠道冻胀量及冻胀力的影响,根据冻土力学及冻土物理学和热辐射原理,利用有限元软件ANSYS按瞬态温变模式加载温度,对衬砌渠道冻胀过程进行动态数值模拟,得到了考虑与不考虑太阳热辐射两种情况下渠道温度、应力和变形场的分布规律.对比可知:考虑热辐射的衬砌渠道冻胀规律与实测正弦型温度变化引起的冻胀规律一致,考虑热辐射的渠基温度大于正弦温度变化法计算而得的渠基温度值,特别是渠道阴坡,考虑热辐射计算的冻胀力、冻胀量均小于正弦型温度变化法计算所得.

Abstract:  Numerical simulation analysis of channel frost heaving dependeds on measured temperature and therefore can not directly forecast channel frost heaving and design. To avoid the default, considering effect of sunlight on frost heaving deformation and frost heaving pressure, based on frost heaving mechanics, frost heaving physics and theory of heat radiation,  dynamic numerical simulation of channel daily frost heaving process was conducted by using  ANSYS to load temperature. Distributions of channel temperature, stress and deformation fields were obtained. By comparison, the frost heaving rule with heat radiation consideration is consistent with that caused by measured sinusoidal temperature change, the soil temperature is higher than that gotten from sinusoidal temperature change method, especially at channel shady position, frost heaving deformation and frost heaving pressure are lower than that calculated by sinusoidal temperature change method.
