梁式跨越直管道强度计算理论分析

Strength Analysis for Direct Pipeline Aerial Crossing Engineering

结合油气输送管道跨越工程设计规范对跨越管道强度计算的要求,利用静力学平衡、弯矩和剪力计算等梁力学理论,对跨越管道先后进行受力分析、内力分析及应力分析。在每个分析过程中,均给出了力学计算式的详细推导过程。同时,利用各种应力计算式对某梁式跨越工程实例进行了强度计算。

Based on the code for design of oil and gas transportation pipeline aerial crossing engineering, the paper has done force analysis, internal force analysis and stress analysis with the static balance, bending moment and shearing force calculation theory. In the process of each analysis, all the detailed derivation of mechanics calculation formula has been given. At the same time, this paper makes strength calculation for one pipeline aerial crossing engineering using all stress calculation formula offered by the paper.
