摘　　要：对传统大跨度种植顶板排水技术在应用上存在的一些问题进行论述,如结构找坡难、轻质找坡漏水、排水不畅、植物烂根死亡等。通过分析上述问题产生的原因,提出并总结防护虹吸排水技术设计及施工应用措施,虹吸排水系统相比传统排水做法可减轻荷载3~4 kN/m^(2),节约成本50~100元/m^(2),节约工期17~21 d。The paper discusses some problems existing in the application of traditional large-span planting roof drainage technology,such as structure slope difficulty,light slope water leakage,poor drainage,plant rot and death.By analyzing the causes of the above problems,the design and construction application measures of protective siphon drainage technology are put forward and summarized.Compared with traditional drainage,siphon drainage system can reduce the load by 3~4 kN/m^(2),save the cost of 50~100 yuan/m^(2) and save the construction period of 17~21 d.
