摘要/Abstract

摘要： 基于台北盆地大量且大范围之地质钻探及地下水量测资料，并应用3D有限差分地下水流分析程序GMS内建之MODFLOW模块，尝试建立台北盆地之区域水文地质概念模型(regional hydrogeological conceptual model)。〖BFQ〗此概念模式藉由台北捷运深开挖中之大规模群井抽水试验结果验证其正确性及适用性。同时，抽水试验中之地下水位泄降量等资料亦被使用于景美砾石层受限(confined)含水层水力参数之分析及评估。最后，边界效应、补注及垂〖BF〗直渗流(leakage)亦将进行初步探讨，做为后续类似工程之参考。

Abstract: The regional hydrogeological conceptual model of Taipei Basin is established by means of 3D finitedifference groundwater flow model, that is MODFLOW, on bais of the numerous and widespread data of geological exploration and groundwater measurement. The regional groundwater flow during the large-scale pumping test of group wells for the deep excavations of Taipei MRT underground stations is simulated by means of conceptual model. The monitoring data of groundwater pressure after drawdown during the pumping test are recorded, so as to analyze and evaluate the nearfield hydraulic parameters of the deep confined aquifer in Taipei Basin. In the end, the effects of boundaries, recharges and vertical leakages on the simulations of groundwater flow are discussed.

Key words: group wells pumping test, conceptual model, Jinmei gravel strata, Taipei Basin, MODFLOW
