摘要
公路经过国家公园、自然保护区及景区等生态环境敏感区域时,多以特长深埋隧道穿越绕避,隧道建设过程中的涌水、渗漏水可能会对水环境造成严重影响,甚至破坏生态环境。为研究隧道建设对生态敏感区地表水源的影响,依托独拉格咱隧道建设,结合隧址区工程地质勘察和物探解译成果,通过对隧址区地表水环境和水文地质专项调查,应用导水裂隙带分析方法和三维地质模型开展隧道建设对隧址区饮用泉点、碧沽天池及千湖山高原湖泊等地表水源的影响,为隧道设计与施工、生态环境保护与管理提供科学依据和技术支持,促使隧道建设和环境保护协调发展。
In eco-environmental sensitive areas such as national parks,nature reserves and scenic spots,highways are mostly bypassed by extra-long deep buried tunnels.In the process of tunnel construction,the possible water inrush and leakage will have a serious impact on the water environment,and even lead to the destruction of the ecological environment.In order to study the influence of tunnel construction on surface water resources in ecologically sensitive area,based on the construction of Dulagza tunnel,combined with the engineering geological survey and geophysical exploration and interpretation results of the tunnel site area,through the special investigation of the surface water environment and hydrogeology of the tunnel site area,the analysis method of water diversion fissure zone and 3D geological model were applied to obtain the impact of tunnel construction on surface water sources such as drinking fountain points in the tunnel site,Bigu Tianchi and Qianhu mountain plateau lakes,so as to promote the coordinated development between tunnel construction and environmental protection when providing scientific basis and technical support for tunnel design and construction,ecological environment protection and management.
