摘　　要：地震地下流体监测井监测的是承压含水层中渗流的变化,这种变化是由渗透系数和导水系数反映出来的,其精度的高低直接影响着地震预测的准确性。本文简述了配线法、直线图解法、水位恢复法及数值模拟法求解承压含水层水文地质参数的原理与步骤。结合具体工程实例,从基本理论、计算过程、计算精度、资料收集等方面对几种求解方法进行了对比研究,为不同工作条件下选择合理的求解水文地质参数方法提供一定借鉴。The seepage variation in confined aquifer during earthquake could be monitored from underground fluid monitoring well, which is reflected by permeability coefficient and transmissibility coefficient. Its accuracy directly affect the prediction accuracy of earthquake. The principles and steps of several methods such as wiring method, linear graphic method, water level recovery method, numerical simulation to solve hydrogeological parameters in confined aquifer is outlined. A comparative study on the principle, calculation process, calculation accuracy, data collection etc. , is conducted as illustrated by a project, which would provide a reference for reasonable solution methods selection under different hydrogeological conditions.
