摘　　要：目前国内城市公共建筑屋面绿化坡度多在20%~50%之间。在屋面坡度超出50%时,防止土体基质“滑坡”成为屋面绿化施工技术一项难题。结合徐州东站东广场上盖屋顶绿化建筑为背景,以保证后期绿化效果和经济成本为原则,参考种植坡屋面防滑系统技术措施原理和无粘性土坡稳定性分析原理,通过拉结带、挡土板和主体结构预埋钢筋作为主要受力支撑构件,利用铺设防滑网格将土体分割成独立的小单元结构等技术措施防止土体滑坡,有效解决了坡度在60%屋顶绿化土体流失和整体滑坡失稳等问题,实现了陡斜坡屋面绿化经济、安全、优质施工,为国内后续施工陡坡屋顶绿化工程建设提供参考和借鉴。At present,the roof greening slope of urban public buildings in China is mostly between 20%and 50%.When the roof greening slope exceeds 50%,preventing the soil matrix“landslide”has become a problem of roof greening construction technology.Based on the roof covered with greening building at the east square of Xuzhou East Railway Station,with the principle of ensuring the greening effect and economic cost in the later stage,and referring to the technical measures of the anti-slip system of planted slope roof and the stability analysis principle of non-cohesive soil slope,the problems of soil loss and overall landslide instability in the roof greening at the slope of 60%have been effectively solved by using the tie belt,retaining plate and embedded steel bars as the main supporting members,and taking technical measures such as laying anti-slip mesh to divide the soil into independent small unit structures to prevent soil landslide.It achieves economic,safe and high-quality construction of steep slope greening,and provides reference for the subsequent construction of steep slope roof greening projects in China.
