复杂地形区域水利工程进场道路和桥隧方案设计研究

Design of Access Road,Bridge and Tunnel for Water Conservancy Project in Complex Terrain Area

水利工程多位于山丘地带,建设线路长,周边环境复杂,工程建设对周边环境影响较大。近年来,随着工程生态保护和建筑景观的要求提升,通过合理利用环境因素以及地势地质条件优化工程设计方案,降低工程对环境造成的影响和破坏有着重要意义。该文以珠江三角洲水资源配置工程罗田泵站进场道路为实例,通过设计方案比选及优化,采用造价略高,但综合效益较好的“三桥一隧道”方案,可供类似工程参考。

Water conservancy projects are mainly located in hilly areas,with long construction lines and complex surrounding environment.In recent years,with the increasing requirements of engineering in ecological protection and architectural landscape,it is of great significance to reduce the impact and damage of engineering on the environment by optimizing the engineering design scheme through rational use of environmental factors and terrain and geological conditions.In this paper,the approach road of Luotian Pumping Station in the Pearl River Delta water resources allocation project is taken as an example.Through comparison selection and optimization of design schemes,the scheme of“three Bridges and one tunnel”with slightly higher cost but good comprehensive benefit is adopted for reference of similar projects.
