文中假定土攘对管道的横向反力遵从Winkler假定,纵向摩阻力服从双线性规律,对带有弯头的管道引入“弹性抗弯铰”以考虑柔度增大的影响,从而建立了平面热力管网的力学模型与通用计算公式。
In this paper, it is assumed that the horizontal reaction of the soil to the pipeline obeys the Winkler assumption that the longitudinal friction obeys the bilinear law, and the “flexible bending hinge” is introduced into the pipe with the elbow to consider the influence of the increase of the flexibility so as to establish the plane Mechanical Model of Heat Pipe Network and General Calculation Formulas.
