近年来,以钢波纹管为代表的新型涵洞在公路工程中的应用越来越多。然而,大直径钢波纹管涵洞的设计和计算理论至今仍不完善,导致设计计算结果和实际结果可能相差较大,同时也制约了这类新型涵洞结构的推广应用。该文结合一实际工程项目,通过对几种涵管管顶土压力计算方法对比以及有限元的模拟分析研究,得出了大直径波纹管管顶土压力的变化规律。
In recent years, the new type of culvert represented by steel bellows has been used more and more in highway engineering. However, the design and calculation theory of large-diameter steel corrugated pipe culverts are still not perfect, which leads to a big difference between the design calculation results and the actual results, and also restricts the popularization and application of this new type of culvert structures. In this paper, a practical engineering project, through the comparison of several methods of calculating the top soil pressure of culvert pipe and the finite element simulation analysis, obtained the law of variation of top soil pressure of large diameter corrugated pipe.
