摘要
通过对珍珠泉井、鲁04井和鲁29井的“SLUG”试验,得出了它们含水层的固有振荡周期和阻尼系数,分析了它们对地震波响应不同的原因。珍珠泉井含水层的固有振荡周期为20.4s,恰好在瑞雷波周期的中间。其阻尼系数只有0.0105s^(-1),它的渗流性强,因而对地震波的响应幅度最大。 三口井孔对地震波响应的观测结果与试验结果同理论研究结果一致。
Based on the 'SLUG' test to the wells of the Pearl spring area,Lu-04 and Lu-29,the period of natural oscillation and damping factor of their aquifers have been obtained,and different reasons of the reponse for them to seismic waves have been analyzed,The natural oscillation period of the wells' aquifer in Pearl spring area is 20. 4s,just within the period of Rayleigh ware. Its damping factor is very small,i. e. 0. 0105s. Its permeability for water in the aquifer is strong. The amplitude of response to seismic waves, therefore, is the greatest.The results of observation of response to seismic waves and the test for the three wells are consistent with that of theoretical study.
