为了探索与提取近期(1～3年)预测强震的应力场判据与指标,本文拟根据地震波与地应力-应变等方面的观测资料,采用环境应力法、震源机制解法和地应力-应变法,研究现今构造应力场和附加应力场的方向与强度及其随时空变化特征同地震的关系,由此归纳和总结出一些预测强震三要素的应力场判据与指标,为强震危险性的综合预测提供应力场的依据。一、研究方法概述 1.环境应力法无论是何种等级的地震,从其震源发出的地震波均携带了震源的各种信息。虽然大地
In order to explore and extract the stress field criterions and indexes of the predicted strong earthquakes in the near future (1-3 years), this paper plans to use the methods of environmental stress, focal mechanism solution and geostress-strain Law, study the current tectonic stress field and additional stress field direction and intensity and its relationship with the characteristics of time and space changes with the earthquake, which summarized and summed up some of the three elements of strong earthquake prediction of stress field criteria and indicators for the danger of strong earthquakes Comprehensive predictions provide the basis for stress fields. First, an overview of research methods 1. Environmental stress method No matter what level of earthquake, seismic waves sent from its sources all carry a variety of sources of information. Although the earth
