| 摘 要： | 地球内部的热应力和重力是驱动地壳运动和地震活动的主要力源，而这些构造应力往往在地壳薄弱处──断层带发生作用。本文从断层在构造应力作用下有关参数发生变化这一情况出发，讨论它们的重力效应，所得结果表明，断层的几何参数和物性参数发生变化时，重力场将产生相应的变化。

| Abstract: | The tectonic stresses,such as the thermo-stress and sravitational force,which generally occur in the weak part of the crust are the main source of crust movement and the earthquake.It is very important to study the effects of fault activity for the purpcae of earthquake prediction.In this paper,the gravity effects caused by the changes of seometric and physical parametere of a fault are discussed when the tectonic stresses applied to the fault without any models siven. |
