针对市政道路下直埋热水管道折角受力问题,采用通用有限元软件ANSYS,基于土弹簧模型建立了热-力耦合有限元模型,对直埋热水管道折角的应力分布特性和影响因素进行分析研究。折角是直埋供热管道设计和施工中最难处理而又不可避免的薄弱环节。道路渠化、竖向变坡、障碍物影响都会导致管道出现折角。由于折角在结构
Aiming at the problem of the pressure on the corner of straight buried hot water pipe under the municipal road, a finite element model of thermo-mechanical coupling based on soil spring model was established by using the general finite element software ANSYS. The stress distribution characteristics and influencing factors of the buried hot water pipeline were studied Analysis. Folding angle is the most difficult and inevitable weak link in the design and construction of buried heat pipe. Road canalization, vertical slope, the impact of obstacles will lead to the emergence of the pipeline angle. As the angle in the structure
