近年来全球气候变迁剧烈，极端天气发生的频率与强度逐渐增高，冲击着水资源供应的稳定性，因而，地下水资源的保护与利用日益重要，后续隧道工程的推动势必面临地下水资源影响议题的挑战。本文提出水文地质调查与三维模式分析在隧道工程中的应用，包括钻井封塞水力试验、施工出水量观测、自记式仪器监测、水文地质参数推估、三维模型建立与率定等重要方法，透过模式分析可了解隧道施工对地下水资源的短期与长期影响，可为隧道工程与环境保护沟通提供参考。

Global climate changes dramatically in recent years. The frequency and intensity of extreme weather occurring gradually increased, which impacts the stability of water supply. The protection and utilization of groundwater resources is, therefore, more and more important. It is expected the assessment of tunnel construction on the influence of groundwater resource would be required in the future. The methods of hydrogeological survey and 3D numerical modeling applied in tunnel construction are proposed in the paper. The major techniques include borehole doublepacker test, water inflow measurement, automatic monitoring instrument, hydrogeological parameter evaluation, 3D conceptual model establishment, model calibration and verification, etc. Furthermore, the possible groundwater loss during excavation and variation of groundwater resource in the longterm would be understood according to the results of transient analysis and steadystate analysis. It can provide the communication between environment protection and tunnel engineering.
