土工格栅在水库生态景观护坡中的应用

Application of Geogrid to Slope Protection of Reservoir Ecological Landscape

广清产业园狗眠岭水库是园区的生态景观调节湖之一,由于园区土建工程建设导致水库边坡垮塌,周边水土流失严重。在遵循固岸减灾、自然生态、安全经济、长效管护的原则下,结合景观设计,在水库边坡治理工程中采用土工格栅加筋土挡墙,并应用设计软件Re SSA对加筋土挡墙进行深层圆弧稳定分析验算,临界计算结果满足最小安全系数,可为今后水库生态景观护坡工程设计与施工提供参考。

Goumian Reservoir is one of the lakes for landscape and ecological regulation in Guangqing Industrial Park.Collapse of the reservoir slope has caused serious soil erosion around the reservoir.Based on the principles of bank consolidation,disaster reduction,natural ecology,safety and economy,and long-term management and protection,geogrid reinforced earth retaining wall is adopted in the slope control project of the reservoir in combination with landscape design.The engineering application design software ReSSA checks the stability of deep circular arc of reinforced earth retaining wall.The critical calculation results meet the minimum safety factor,which provides a reference for the future design and construction of slope protection project of reservoir ecological landscape.
