摘　　要：三峡井网是我国第 1个以监测水库诱发地震的地下水前兆为目的的专业网 ,由 8口观测井构成。其中 4口井台有水温和土氡观测 ,3口井台有降雨、气压与气温观测 ,另有一处库水位观测 ;每口井台中均有水位动态观测。观测项目共有 2 6项。文中主要介绍三峡井网的观测技术系统 ,其中包括井网的技术系统与井台的技术构成 ,各类仪器设备的技术指标与安装调试 ,相关的供电、通讯与防雷等技术支撑设施。此外 ,还简要介绍了观测技术系统的运行及其基本结果。The Three Gorges well network is the first professional network in China established for the purpose of monitoring the groundwater precursors of reservoir induced earthquake. It is composed of 8 observation wells. In addition to observe the change of water level, 4 wells are enabled to measure water temperature and soil Radon, 3 wells are enabled to measure rainfall, atmospheric pressure and temperature, and 1 well can be used to observe the water level of the reservoir. The observation items are totaled 26. The present paper introduces in detail the technical system of the observations used in the Three Gorges well network, including the technical system of the whole network and each well, the technical index, installation and adjustment of every sort of instruments and equipments, as well as the corresponding supporting facilities such as the power supply, communication and lighting arrester. In addition, the running of the technical system of these observations and its preliminary results are also introduced briefly.
