摘要
通过对城市道路路面病害的调查,针对现有城市沥青混凝土路面的病害情况,应用有限元模拟方法,建立市政道路三维结构力学计算模型,分析道路结构层的力学特征、构筑物的形式与影响范围等因素变化下的特征行为,得出市政道路的地下管网存在对路面整体结构的影响.同时,结合现状的病害调查分析,经过数据与现状对比,探索含有地下管网系统的路面病害潜在原因,依据分析结果给出相应的病害防治对策,为后期的设计提供技术参考,为施工提供有效的防治理论.
Abstract
Based on the disease investigation of urban road pavement,aiming at the disease situation of existing urban asphalt concrete pavement,the three-dimensional structural mechanics calculation model of municipal road is established by using the finite element simulation method to analyze the characteristic behavior of road structural layer under the change of factors such as mechanical characteristics,structure form and influence range.It is concluded that the underground pipe network of municipal roads has an impact on the overall structure of the road pavement.Combined with the disease investigation and analysis of the current situation,the potential causes of the pavement disease containing the underground pipe network system are explored through the comparison of the data and the current situation.The corresponding disease prevention and control countermeasures are given according to the analysis results,providing the technical reference for the later design and providing the effective prevention and control theory for the construction.
