Research On Identification And Control Countermeasures Of Urban Road Concealed Concealed Defects Based On Ground Penetrating Radar

In recent years,with the development of the city,to the rapid growth of population,population density increasing,the city obtained the development and expansion,which is becoming more and more heavy burden on municipal construction,with the gradual expansion of city scale,especially for large and medium-sized cities of the urban traffic congestion,etc.,the municipal road and parking lot field concealed defects such as effective identification and reasonable repair increasingly become a prominent problem.As the main component of municipal engineering,roads and parking lots are one of the main carriers of urban population flow.The increasing disrepair of roads and parking lots in cities,such as the dynamic load of heavy vehicles,will further deteriorate the quality of roads and parking lots and reduce their service life.How to identify and manage hidden concealed defects in congested roads in a timely manner without taking up too much time and capital cost has become one of the important topics to be explored urgently.Therefore,seeking for an effective identification technology and summarizing a set of relatively perfect prevention and control strategies has become the starting point of this paper.Paper first to concealed defect disease research status quo of urban road and parking lot as the breakthrough point,through summarizing and analyzing the existing survey based recognition method,is put forward by geological radar based on city roads and parking lots of concealed concealed defects of nondestructive identification method,and in view of the city road conditions to improve the vehicular geological radar systems,and pull in view of the parking lot,in a typical urban road and parking lot practical engineering testing requirements as the foundation,has carried out the relevant test;Secondly,through the analysis results and verification of system cases,the spatial distribution of hidden concealed defects is formed,which provides specific targets for further governance.Through re-inspection,expert review,deflection detection and other means to test the results,to further improve the survey accuracy,to ensure the effect of identification;Finally,this paper also introduced and summarized the management strategies of these hidden diseases in detail,the author expounds the shortcomings in the management of relevant functional departments and the specific countermeasures.A set of management information system of concealed defect identification,governance and maintenance is preliminarily designed,so as to provide more references for the identification and treatment of hidden diseases on urban roads and parking lots in China.
