摘要:
由于隧道施工、采矿等人类工程活动的影响,导致重庆缙云山、中梁山、铜锣山和明月山(简称“四山”)地区地下水严重疏干,植被损毁,直接影响到重庆都市经济圈5473 km2范围的生态环境。通过实施20个钻孔、总进尺4646 m的钻探工程,进行抽水、压水试验,对“四山”地区地下水水质、水量进行评价。应用井中电视成像仪在孔内进行连续成像,利用编录资料及孔内成像资料,建立三维可视化地质模型。完井后在孔内安装监测仪器,建立长期观测站点,在办公室电脑上,即可实时监测地下水动态变化,并自动生成各类图表,为相关部门提供基础水文地质参数,为城市规划、工程设计施工、政府决策提供第一手资料。
Abstract:
The influence of the tunnel construction, mining and other human engineering activities leads to the serious drainage of groundwater in Chongqing mountainous area, vegetation destruction, which directly affects the ecological envi-ronment of the 5473km2 range of Chongqing urban economic circle.Through the drilling engineering of 20 holes with total drilling footage of 4646m, pumping and water pressure tests were carried out, the evaluation of groundwater quality and quantity in the mountainous area was made.Application of wells TV instrument for continuous imaging in the hole, using the hole logging data and imaging data, established the three-dimensional geological model.Monitoring equipment installed in the hole after completion as long-term observation sites.Real-time monitoring of groundwater dynamic changes can be re-alized by office computer and various types of charts can be automatically generated to provide hydro-geological parameters for the relevant departments and offers first-hand information for urban planning, engineering design and construction as well as government decision making.
