地下水在地壳中普遍存在,具有流动性和难压缩性,所以它能直接而灵敏地反应岩石中的应力、应变状态。岩体裂隙产生、发育及向断裂过渡等是地震成因研究的核心问题。因此地下水的动态分析是寻找和解释地震前兆、开展地震预报的钥匙。通过对邢台、唐山等多次地震的深入总结,证实地下水动态是一个很有前途的方法。据此,国家地震局在1978年把地下水列为重点攻关项目之一。经过七年不懈努力,全国
Groundwater is ubiquitous in the earth’s crust. It is fluid and difficult to compress so that it responds directly and sensitively to stresses and strains in the rock. Rock mass fissure generation, development and transition to the fracture is the core issue of earthquake research. Therefore, dynamic analysis of groundwater is the key to find and explain earthquake precursors and carry out earthquake prediction. Through the in-depth summary of many earthquakes in Xingtai and Tangshan, it is a very promising way to confirm the groundwater dynamics. Accordingly, the State Seismological Bureau in 1978 to groundwater as one of the key research projects. After seven years of unremitting efforts, the whole country
