在过去的十年里，人们对屋顶排水系统的理解和设计方式发生了重大变化。特别是，虹吸式屋顶排水系统的规定和预期性能的信心已经逐步发生变化。这些变化发生的同时，随着可持续城市排水系统的广泛接受和气候变化背景下公众对雨水泛滥的更多关注，城市排水设计总体上发生了革命性的变化。本文详细考虑了如何设计屋顶排水系统以及它们应该如何执行。特别注意的是，在公认的设计方法的弱点。还考虑了“创新”屋顶排水相关方法，如绿色屋顶和雨水收集。实际应用：在过去的几年里，屋顶排水系统的规定和设计发生了许多变化。在大型建筑物上，“虹吸式屋顶排水系统”等技术现已司空见惯，由于“绿色屋顶”具有“绿色”发展的潜力，因此对“绿色屋顶”的需求日益增加。基于正在进行的研究，本文详细介绍了如何有效地设计这些不同类型的屋顶排水解决方案，以及预期的性能水平。
The past 10 years have witnessed significant changes in the way roof drainage systems are understood and designed. In particular, there has been a stepchange in the confidence with which siphonic roof drainage systems may be specified and expected to perform. These changes have occurred whilst urban drainage design in general has been revolutionized by wider acceptance of Sustainable Urban Drainage Systems and greater public concern regarding pluvial flooding within the context of climate change. This text considers, in detail, both how roof drainage systems are designed and how they should be expected to perform. Particular attention is drawn to weaknesses in accepted design methods. Consideration is also given to ‘innovative’ roof drainage related approaches such as green roofs and rainwater harvesting. Practical application: Over the past few years there have been many changes in how roof drainage systems are specified and designed. On large buildings, technologies such as ‘siphonic roof drainage’ are now commonplace and there is an ever increasing demand for ‘green roofs’ to be specified due to their potential to ‘green’ developments. Based on ongoing research, this paper details how these different types of roof drainage solutions can be efficiently designed and what levels of performance can be expected.
