| 摘 要： | 根据弹性力学的基本理论 ,建立了水平矩形薄板模型 ,推导了计算此类薄板影响地倾斜的基本公式。通过该模型的模拟计算 ,分别得出了由大楼质量造成的附加引力位对观测点水平摆的偏转角度和大楼负荷产生的地倾斜 ,并针对厦门地震台的实际情况 ,讨论了大楼对地倾斜观测的影响。

| Abstract: | In the light of basic theory of elastic mechanics,a model of horizontal rectangle thin plate is put forward and its basic formulas for calculating ground tilt are given in this paper.Through simulating calculation by the model,we have respectively gained the deflection angle of pendulum at observation site which is caused by adding gravitational potential of building mass and the ground tilt which is caused by building load.In accordance with the practical situation of the Xiamen seismostation in 1997,we also discussed how the building affects the ground tilter at last. |
