The concept and method of fuzzy sets were proposed only more than ten years ago。And they have been used in many scientific fields nowadays.The authors try to introduce the knowledge of fuzzy mathematics into earthquake prediction. Tke-refore, "normality" and "abnormality" are preliminarily explored by using fuzzy language. The membership functions of the single precursor abnormality and multiple precursor abnormality are preliminarily determined, the method of programming the earthquake prediction is boldly imagined and internally examined hy using two simple cases as samples, and finally, some preliminary results are obtained. It is considered that the prospect for using the technique of fuzzy mathematics is captivating.

模糊集的概念和方法是十多年前才提出来的,现在已在很多科学领域中得到了应用。作者试图把模糊数学的知识引入地震预报。为此采用模糊语言对“正常”、“异常”作了初步探讨。初步确定了单项前兆异常和多项前兆异常的隶属函数。从方法上对编制预报程序作了大胆的设想。并以两个简单实例为样本作了内检,取得了一些初步结果。我们认为,采用模糊数学技巧具有诱人的前景。

In order to resolve the problem of earthquake prediction and to lay down the rational seismic countermeasure, the precursors abnormalities in Jinn province of the Haicheng earthquake, the Tangshan earthquake, within Jilin province the moderate earthquake, etc. are specially discussed by seismological researchers of different degrees, which promotes strongly the development of seismic example studies of Jilin province,and enhances the using value of precursory data .In this paper, the moderate earthquakes in Jilin province, moderate to strong earthquakes in neighboring region and strong earthquakes in the west Pacific Ocean are extensively studied with data of varied precursory subjects, then the earthquake reflecting ability is analyzed and discussed.

本文清理了吉林省地震前兆台网在省内中等地震,邻区中强以上地震、西太平洋地震带大震前记录到的14次前兆异常.通过震例统计,筛选出省内前兆映震敏感测点和敏感测项.根据映震范围曲线求出最低映震震级为3.0级左右,线性区内最大映震距离为600~800km.对5级地震的反映距离为200~300km.

On the basis of the geologic structure and the observation data for over 30 years at Dahuichang station,Beijing, mutual action and relation between crustal deformation and underground water are studied and its model of hydrogeologic mechanics is built. The results show that fault movement is acted by tectonic stress and subsurface fluid force produced by underground water together. The change of the manner that how the fault is forced can affect on crustal deformation, underground water level and their mutual...

On the basis of the geologic structure and the observation data for over 30 years at Dahuichang station,Beijing, mutual action and relation between crustal deformation and underground water are studied and its model of hydrogeologic mechanics is built. The results show that fault movement is acted by tectonic stress and subsurface fluid force produced by underground water together. The change of the manner that how the fault is forced can affect on crustal deformation, underground water level and their mutual relation, and make the curve shape of observation data change. The seismic precursory anomaly of crustal deformation and underground water level are non-cyclic changes resulted from the mutual action of the tectonic stress of earthquake preparation and fluid force produced by rain, underground water.A view of seimic precursor of “double force source” is put forward, its main points are: Earthquake source body dilate to produce crustal deformation and subsurface fluid abnormality which gives rise to the subsurface fluid force influencing earthquake preparation,development and precursor occurrence. Seimic precursor occurrence is the result from the action of “double force source”, namely tectonic stress and the subsurface fluid force. The tectonic stress is primary and the subsurface fluid force is additional or modulating,that only the subsurface fluid force mechanicaly couplling with the tectonic stress of earthquake preparation on its enhancement process may modulate and induce earthquake precursor abnormality, and promote earthquake occurrence.

依据北京大灰厂台地质构造及30多年的观测资料,建立水文地质力学模型,系统地研究了地下水与地壳形变的相互作用及关系。研究表明,断层活动受构造应力和降雨、地下水产生的流体力共同作用;断层受力方式的改变对地壳形变、地下水位及相互关系产生影响并使观测曲线形态发生变化;地壳形变与地下水位前兆异常是在地震孕育构造应力和降雨、地下水引起的流体力共同作用下产生的非周期性变化。据此提出地震前兆异常的“双力源”观点,震源体膨胀(扩容)产生变形并引起地下流体异常,地下流体异常产生流体力,流体力影响地震孕育、发展和前兆的产生;地震前兆的产生是“双力源”即构造应力和流体力联合作用的结果;构造应力的作用是第一位的,地下流体力则是附加的、调制性的,只有那些能与地震孕育构造应力增强过程产生力学耦合的地下流体力才能调制与诱发出地震前兆异常并促使地震发生。
