张应力在地震过程中的作用

THE ROLE OF THE STRETCHING STRESS IN THE EARTHQUAKE PROCESS

摘要:

本文根据断裂力学的基本结论,地质学对断裂形成过程的认识以及一部分地震事实,讨论了张应力在地震断裂形成过程中的作用。本文认为:张应力在地震过程中起着十分积极的作用。这是对目前一般认为地震是由剪切破坏形成的观点的必要补充。

Abstract:

This paper, based on the basic conclusions of the rupture mechanics, on a geological understanding of the rupture formation process as well as on some factual accounts of earthquakes,discusses the role of the stretching stress during the process of seismic rupture formation. It holds that an active,role is played by the stretching stress in the earthquake process.This serves as a necessary supplement to the present point of view that earthquakes result from shearing break.
