高填方路基钢波纹管涵洞力学性能及经济效益分析

钢波纹管涵洞有管节薄、质量轻、便于叠置捆扎，存放运输方便、施工组装工艺简单、生产周期和施工期短等特点，同时波纹管涵洞适应能力强，受力条件好，造价低，故其具有很广阔的应用前景。目前，国内对于波纹管力学性能研究还较少。通过对高填方钢波纹管涵洞进行野外现场试验，结合相关钢波纹管涵洞知识，从不同方面研究了钢波纹管涵洞的力学性能，同时进行了波纹管与盖板涵的造价比较，为波纹管在工程和设计中应用具有重要指导意义。

Mechanical Performance Study of High-filled Corrugated Steel Pipe Culvert

Corrugated steel pipe culvert has many characteristics, such as thin pipe, light weight, easy packing, convenience in storage and transportation, simple construction , short production cycles and construction period,meanhile corrugated pipe culvert has many advantages,such as good adaptable a- bility, good mechanical performance, low cost, so it has a very broad application prospects. At present, there are less studies on mechanical performance of corrugated steel pipe culvert in our country. This pa- per has field test research under high-stacked soil, and analyze the mechanical performance combining with related corrugated steel pipe culvert knowledges from different areas,it also have a contrast with slab culvert about their construction costs, and has important directive significance for application of corrugated steel pipe culvert in engineering and design areas.
