摘要

波纹钢管廊结构具有受力性能优、施工时间短、造价低、环保性能好等优点。为深入了解波纹钢管廊结构的承载机制、破坏特征及装配化技术、规范化断面形式、土体加固方法及措施等关键设计方法，对美国、加拿大、澳大利亚等公路、铁路工程中的排水沟、地下通道、立交工程中波纹钢管道结构的应用情况进行介绍，分析梳理波纹钢管道在国外的工程应用、规范编制、技术特征和设计施工方法，并对波纹钢管结构的荷载计算、强度验算、设计流程和方法进行详细分析。结合国内波纹钢管廊建设技术的发展需要，从建设环境、结构断面形式、装配化、围护土体加固、最小埋置深度等方面探讨波纹钢管廊建设中存在的问题及发展趋势，提出对波纹钢管廊建设关键技术的研究建议。

Abstract

The corrugated steel utility tunnel has the advantages of excellent mechanical performance, short construction period, low cost and good environmental protection performance. In order to deeply understand the structural bearing mechanism, failure characteristics and the key design methods such as assembly technology, crosssection type of standardized structure and soil reinforcement methods, the application of corrugated steel utility tunnel structure in drainage ditch, underground passage and overpass engineering in highway and railway engineering in US, Canada, Australia, etc. is introduced. And then the application of corrugated steel utility tunnel, standard compilation, technical characteristics and design and construction method out of China are analyzed, and the key factors including load calculation, strength calculation, design flowchart and methods of corrugated steel pipe are analyzed in detail. Based on the development needs of corrugated steel utility tunnel construction technology in China, the problems and development trend of corrugated steel utility tunnel construction are discussed from the aspects of construction environment, structural crosssection form, assembly, reinforcement of retaining soil and minimum embedded depth, and the research suggestions on key technologies of corrugated steel utility tunnels are put forward.

Key words： corrugated steel pipe; utility tunnel; structural shape; load pattern; strength calculation; fabricated structure
