Abstract: Field investigation on hydrogeological environment around Changping well reveals that the anomalous uprise of 'water table begining from Oct. 1988 was mainly caused by the leakage of water from the channel leading to Shisanling Reservoir, but not the precursor of Datong-Yanggao earthquake in Shanxi Province in 1989.

摘要： 本文通过对昌平观测井周围水文地质条件的现场调查与深入研究,论述了该井水位自1988年10月以来出现的大幅度抬升的原因,是由于十三陵水库引水途中通过古河道的渗漏补给引起的正常动态,并不是1989年10月大同-阳高地震的前兆异常。
