摘　　要：大地景观屋面融合了覆土建筑和屋顶绿化的特点,以大面积人工多维复杂曲面为空间载体,衔接屋面与地面,形成连续的植物覆被表面。衢州体育公园是大地景观屋面工程的代表性案例,其景观效果依赖于草坡完成面的设计建造,须突破面积巨大、坡度复杂、与建筑结构协调及环境适应性等难点。针对衢州体育公园大地景观屋面覆土草坡的草种和种植基质选择、固土系统构建、雨洪管理系统等方面展开技术应用研究,结果显示:中华结缕草单属品种种植优于混播草种,宜选择40 cm以上达标种植土作为种植基质;坡面固土在屋面双重结构条件下通过在构造中增加技术支撑层改善覆土草坡基本构造,并通过优化钢绞线和装配式钢结构锚杆的措施升级土工格室装配技术,最终形成平面化整为零、断面分层抗滑的屋面固土体系;雨洪管理系统须通过构建地表径流排水和土壤下层下渗排水2套排水系统,形成与建筑结构和设备紧密结合的排水体系。衢州体育公园的建成效果有力地验证了工程应用研究成果的可靠性、有效性和品质效果,可供后续相关工程参考与借鉴。The landscape roof integrates the characteristics of soilcovered buildings and roof greening,using large artificial multidimensional complex curved surfaces as spatial carriers to connect the roof and the ground,forming a continuous vegetated surface that integrates the building roof with the landscape.Quzhou Sports Park is a representative case of large-scale landscape roof engineering.Its landscape effect relies on the design and construction of the grass slope,which must overcome difficulties such as the massive scale,complex slopes,coordination with the building structure,and environmental adaptability.This article focuses on the technical application research of the grass species and planting substrate selection,soil fixation system construction,and stormwater management system of the soil-covered grass slope of the large-scale landscape roof of Quzhou Sports Park,and has obtained a series of conclusions and achievements:planting Zoysia sinica is better than mixed grass species,and it is advisable to choose standard planting soil with the depth of 40 cm as the planting substrate;slope soil fixation improves the basic structure of the soil-covered grass slope by adding a technical support layer to the basic structure of the grass roof,and upgrades the geocell assembly technology to form a roof soil fixation system that divides the plane into zones and layered anti-slip sections;the stormwater management system must construct two drainage sub-systems:surface runoff drainage and underlying soil infiltration drainage,to form a drainage system that is closely integrated with the building structures and equipment.The completed effect of Quzhou Sports Park has effectively verified the reliability,effectiveness,and quality of the engineering application research results,and also provided feedback that can be used for reference in subsequent projects.
