埋地竹塑复合材料管道的受力分析研究

摘要

The stress of buried bamboo plastic composite pipe is analyzed in experiment, theory, and calculation. Supposing the pipe and soil are belongs to linear elasticity materials, and isotropic and uniformity from every direction, considering the weight of pipeline, soil pressure, ground load, tubing pressure and temperature stress, the paper analyzes the law about pipeline deformation and stress under different conditions of material, wall thickness and burial depth, by using ANSYS software of finite element analysis.%　　对埋地竹塑复合材料管道的受力状态进行了实验与理论、计算分析。假定管道、土均为线弹性、各向同性、均匀性，且考虑了管道自重、土压力和地面荷载、管内压力以及温度应力的影响；选用ANSYS通用有限元分析软件，对管、土接触面进行了不同条件下，管材、壁厚、埋深情况的分析，总结出管道变形、受力的规律等。
