含有地下管道的沥青混凝土路面结构力学分析

摘要

Against the existing diseases of asphalt concrete pavement with underground pipeline, road structural mechanical model has been established using finite element method to analyze the mechanical behaviors under modulus of resilience of backfilling material, buffed depth of pipeline and groove form. Thus the force distribution and range of underground pipeline on pavement structure have been obtained, and then the results are compared to the diseases of the surveyed pavement, which provide theoretical reference for concrete pavement structural design and site construction as well as for improvement of pavement structural performance.%针对现有含有地下管道的沥青混凝土路面的病害现象，应用有限元方法，建立了道路结构力学计算模型，研究分析道路回填材料的回弹模量、管道埋深及沟槽形式等因素变化下的力学行为，得出地下管道的存在对路面结构影响受力分布规律与范围，并和调查路面的病害情况进行对比，为沥青混凝土路面的结构设计与现场施工及改善路面的结构性能提供了理论参考。
