摘要:
井-含水层系统水文地质参数是地下水/含水层水流模型中的关键参数,这些参数通常通过室内实验、野外试验和模型反演获取。基于新10井水位对远场地震的同震响应,通过频谱法分析了该井水震波与地震波的相关性,提出了一种利用水震波信号(主要是瑞利波引起)反演获取承压含水层水文地质参数的方法。结果表明新10井水震波与地震波在变化形态、频谱特征上均具有很好的一致性,估算得到的新10井-含水层系统的储水系数值为1.33×10-5~1.64×10-5,渗透系数值为57~87 m/d。提出的承压井-含水层系统水文参数估算法具有很好的实用性,可为地下水管理、地震机理分析等提供一种新的技术方法。
Abstract:
Hydraulic parameters of a well-aquifer system are critical for groundwater flow models of a groundwater/aquifer system. These parameters are usually obtained through laboratory experiments, field tests and model inversions. Based on the coseismic responses of groundwater levels in the X10 well to distant earthquakes and the correlations of groundwater and seismic waves obtained from spectral analyses, this paper presents a methodology for estimating hydraulic parameters of a confined aquifer using groundwater wave signals (mainly caused by the Rayleigh waves). The results show a good agreement between the variations and spectrum characteristics of the groundwater waves and seismic waves in the X10 well. The estimated storativity of the X10 well-aquifer system is 1.33×10-5~1.64×10-5, and the hydraulic conductivity is 57~87 m/d. The methodology for estimating hydraulic parameters of the confined well-aquifer systems presented in this paper is practical and can provide a new technical approach for groundwater management and the analyses of seismic precursory anomalies.
