本文用在均匀弹性平面半空间上迭覆一同样介质的斜面体,来模拟有坡度的山体,在二维空间里严格地推导了山体内任一点的变温函数、温度应力、热应变、垂直热形变和热倾斜等一整套热弹效应公式。结果表明,热弹效应与地形有很大关系。对于水平应变和地倾斜,坡度越大,热效应也越大;垂直形变则相反。因此,对于地震前兆观测来说,估计这些热弹效应的大小是很重要的,特别是在选台建台时必须考虑这一因素。 In this paper, we simulate the slope of a mountain body with the same medium in a uniform elastic half-space, and strictly deduce the temperature-change function, temperature stress, thermal strain and vertical heat in any point in the mountain in two-dimensional space Deformation and thermal tilt and a set of thermoelastic effect formula. The results show that the thermoelastic effect has a great relationship with the topography. For horizontal strain and ground tilt, the greater the slope, the greater the thermal effect; the vertical deformation is the opposite. Therefore, it is important to estimate the magnitude of these thermo-bullet effects for earthquake precursor observations. This factor must be taken into account especially when choosing stations for station building.
