Highway Management Office, the Shanghai Municipal Engineering Design Institute, and Shanghai Tongji University conducted dynamic and static tests on metal corrugated culverts. The results showed that they could meet the design and use requirements, fill the gaps in China, and were quickly promoted and applied. Metal corrugated pipes were put into the construction of Qinghai highway. Three years of practice proved that metal corrugated pipes fully meet the requirements of culvert construction in the cold areas of the North. Practice has shown that using metal bellows instead of reinforced concrete for culvert construction has incomparable advantages in terms of construction cycle, construction cost, and environmental protection significance, and using metal bellows for culvert construction. It can greatly improve the comfort and safety of road driving and avoid the appearance of "wrong platform jumping" in the culvert of the road,
