Well periphery pavement structure design method and system based on vehicle dynamic load analysis

Abstract

The invention discloses a well periphery pavement structure design method and system based on vehicle dynamic load analysis, and the method comprises the steps: carrying out monitoring and flatness testing of a well periphery pavement disease to acquire inspection well settlement data, well periphery pavement flatness testing data and non-well periphery pavement flatness testing data; constructinga vehicle model; constructing a well periphery pavement model based on the well periphery pavement flatness test data; constructing a non-well-periphery pavement model based on the non-well-peripherypavement flatness test data; constructing a well lid deformation and inspection well settlement model based on the inspection well settlement data; combining the vehicle model, the well periphery pavement model, the non-well periphery pavement model and the well lid deformation and inspection well settlement model into a vehicle-pavement-well lid three-dimensional integrated simulation model; obtaining the vehicle load when the vehicle passes through the inspection well and the road surface around the well so as to analyze the dynamic load of the vehicle; based on vehicle dynamic load analysis, considering a vehicle dynamic load coefficient and designing the pavement structure.

Description

Technical field [0001] The present disclosure relates to the technical field of urban road engineering, and in particular to a method and system for designing a road surface structure around a well based on vehicle dynamic load analysis. Background technique [0002] The statements in this section merely mention background technologies related to the present disclosure, and do not necessarily constitute prior art. [0003] The urban pipeline network is an important part of the urban infrastructure and is called the "urban artery", and the inspection well is an essential part of the urban pipeline network. In the construction of urban pipeline network, inspection wells should not be arranged on urban roads. However, due to the arrangement of other pipeline networks and the space constraints of road width, a considerable number of inspection wells are arranged on urban main roads, secondary roads and branch roads. Within the scope of the road, it has become a weak part of the entire...

AI Technical Summary

Problems solved by technology

Larger vehicle dynamic load is one of the important reasons for frequent pavement diseases around wells, and vehicle load is a key parameter in pavement structure design. However, the existing vehicle dynamic load analysis methods are mostly based on theoretical analysis, which is difficult to analyze , low accuracy

If the deformation and vibration of the manhole cover, the settlement of the inspection well, and the difference between the smoothness of the pavement around the well and the conventional road surface are considered, the existing theoretical methods are difficult to obtain accurate vehicle dynamic loads, and cannot support the pavement around the well inspection well on urban roads.
