摘    要:本文介绍了济南珍珠泉井水固有振荡试验结果.利用振动理论和Cooper水井-含水层模式对试验进行了解释.计算出珍珠泉水井-含水层系统的阻尼系数和固有振动的角频率.该系统阻尼系数小,角频率恰好和瑞利波角频率相近,因此珍珠泉井水位对地震瑞利波响应的振幅特别大.井水固有振荡试验是一种简便易行、经济迅速的方法,它比其它现场试验方法更宜于推广应用.

关 键 词:水井  固有振荡试验  阻尼系数  固有频率

Abstract:A test of natural oscillation of water level in the well Pearl Spring in Jinan has been carried out. By using vibration theory and he Cooper's model of the well-aquifer. The result has been explained. On the basis of the test the damping factor and angular frequency of natural oscillation cf the well aquifer have been calculated. The damping factor is smaller, and the angular frequency just is close to the that of Rayleigh's wave. Therefore the amplitude of response of the well Pearl Spring to the seismic Rayleigh's wave is specially great. The test of natural oscillation of well level is a method simple and easy to do, economical and seift. It is more suitable in extension and application than other tests in situ-
Keywords:Well  Test of natural oscillation  Damping factor  Natural frequency
