摘要
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, the inclined plane overlaping on the same medium in a samispace with homogeous elastic medium is used to simulate the sloped mountain masses, and in a two-dimension space, a set of thermoelastic effect formulas have been inferred strictly for temperature change function, tempsrature stress, thermostrain, vertical thermo-deformation and thermo-tilt at any point in a mountain mass. The results show that the thermoelastic effect is closely related to landform. For the horizontal strain and crustal-tilt, the larger the slops, the greater the effect is, conversely,the vertical deformation is smaller, For the observation of seismic precursors, landform is one of the important factors which must be considered during a station site selection. The result given in this paper is much more strict and practical than other previous ones.
