Abstract: Based on the calculation model for circular curved beam in elasticity mechanics, the governing differential equation of elastic circular curved beam under the effect of dead weight, uniform internal water pressure, full tube water load and shearing force on circular section is established, and the exact formula of elastic theoretical solution for internal force and displacement of transverse structure of overhead beam-supported circular pipe is given.

Key words: overhead pipe, circular curved beam, internal force, exact solution

摘要: 采用弹性力学圆弧曲梁计算模式,建立了架空梁式圆管受自重、均匀内水压力和满管水重荷载作用,并考虑圆截面剪力作用下的弹性圆弧曲梁控制微分方程,给出了架空梁式圆管横向结构内力与变位的弹性理论精确解计算式。
