粘弹性半空间断层活动的重力效应(讨论)
GRAVITY CHANGE DUE TO FAULTING IN A VISCOELASTIC HALF-SPACE
-
摘要: 本文指出,可应用对应原理及沃尔什与赖斯的弹性解作面积分,即可算出粘弹性半空间断层活动所导致的重力变化.结果表明,重力变化并不依赖于粘弹性质,而且与滑移历史有预期不到的简单关系.Abstract: We show how gravity changes due to faulting in a viscoelastic half-space can be calculated through a surface integral by applying the correspondence principle to Walsh and Rice's (1979) elastic solution. Our results show that gravity changes are independent of viscoelastic properties, and are related to the slip history in an unexpectedly simple manner.
