组合型加筋土挡墙在抽水蓄能电站上下库连接道路中的应用

Application of Combined Reinforced Earth Retaining Wall in the Connection Road of Upper and Lower Reservoirs of Pumped-storage Power Station

深圳抽水蓄能电站上下库连接道路深谷冲沟路段采用组合型加筋土挡墙结构,减少了植被破坏和水土流失,建成至今已安全运行8年,未出现结构变形失稳。介绍了组合型加筋土挡墙的方案比选、结构形式、施工工序和质量控制措施,为今后类似项目施工建设积累了宝贵的工程经验。

The combined reinforced earth retaining wall structure is adopted in the deep valley gully section of the connection road between the upper and lower reservoirs of Shenzhen Pumped-storage Power Station,which can reduce vegetation damage and soil erosion.Up to now,it has been operated safely for 8 years without structural deformation and instability.The scheme comparison,structural form,construction process and quality control measures of combined reinforced earth retaining wall are introduced herein,which has accumulated valuable engineering experiences for similar projects in the future.
