摘要
针对周边房屋密集、河流较多的地段,富水区的隧道施工容易对周边水环境产生不良影响。本文以福鼎山隧道为对象,结合工程地质勘察和水文试验资料,估算隧道正常涌水量,分析公路隧道施工对周围地表水及地下水环境的影响,并提出相应的工程处置措施和环境保护对策。研究结果表明,隧道施工过程中,由于开挖、加固、施工机械等施工条件,将引起周边环境的废水污染、地下水流场变化、水土流失等现象,对此,应加强对隧道洞身渗水流量、水库影响段落、地表深孔水位等进行监测,最大限度降低地下水、地表水的流场变化、并合理处置施工废水的排放。
In view of the surrounding areas with dense housing and many rivers,tunnel construction in water-rich areas is easy to have adverse effects on the surrounding water environment.Therefore,taking Fudingshan Tunnel as the object,combined with engineering geological investigation and hydrological test data,the normal water inflow of the tunnel is estimated,and the influence of highway tunnel construction on the surrounding surface water and groundwater environment is analyzed.And put forward the corresponding project disposal measures and environmental protection countermeasures.The research results show that during tunnel construction,due to excavation,reinforcement,construction machinery and other construction conditions,the surrounding environment will cause waste water pollution,underground water flow field changes,soil erosion and other phenomena.In this regard,the seepage flow rate of tunnel body,the affected section of reservoir,and the surface deep hole water level should be monitored.To minimize the variation of groundwater and surface water flow field,and rationally dispose of construction wastewater discharge.
