中强地震前承压井水位固体潮和地震活动响应比的变化

以山西省大同—阳高２次地震与忻州地震为例，利用尹详础教授的加卸载响应比理论，研究了山西承压井水位与含水层固体潮体应变的响应比、地震活动的响应比变化特征。表明，在多数地震前，井水位的响应比有大于背景值１、地震活动大于背景值２的高值异常变化，且具有突变特点。说明响应比方法对山西省中强地震有较好的预报效能

Variation Character of Earth Tide of Water Level of Artesian Well and Response Ratio of Seismicity before Strong Moderate Earthquake

Taking the 2 earthquakes at Datong Yanggao and a Xinzhou earthquake in Shanxi for example,the variation characters of the response ratio of the water level of artesian water level and the body strain of the earth tide of the water bearing bed,the response ratio of the seismicity in Shanxi were analyzed by the load/unload response ratio theory.The conclusion suggested that there are the high value anomalies of the response ratio>1 of the water level and the background value>2 of the seismicity,and the sudden change before most earthquakes.The method of the load/unload response ratio has a fairly good prediction ability for the strong moderate earthquakes in Shanxi province.
