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.
