Study On The Action Of Dynamic Response To Moving Vehicle Load On Pavement

Following the reform and opening up and development of the nationaleconomy,China’s highway get rapid development, countries are of the utmost importanceto road traffic engineering construction, especially in nearly a decade, has been built andbeing built up to thousands of all kinds of road engineering projects. However with thedevelopment of economy, the highway traffic load, the increase of traffic volume andvehicle speed, pavement structure need to have higher reliability and durability, its safetyand comfort are also more and more aroused people’s wide attention, the construction ofroad engineering and science and technology also has a new request. In larger underdynamic load of vehicles on the road driving process on the actual effect and the effectof pavement under the action of static load model is gradually increasing the gapbetween. For optimizing the design and construction of pavement structure and reducethe late road maintenance fees, study the destruction mechanism of pavement structureunder dynamic load is very necessary. Overloading transfinite phenomenon and thevehicle dynamic load is affect the service life of pavement structure early damage andreduce the key factors.Vihicle on the pavement structure dynamic load is a major cause of road damageloss, so the pavement response under the action of vehicle dynamic load is verymeaningful. Analysis is a complex problem of dynamic response of asphalt pavement, inthis paper, on the basis of predecessors’ research results, the asphalt pavement in the fieldof elastic and viscoelastic layered system theory in the field of study on theory,respectively. Through the application of Laplace and Hankel integral transformation andmathematical tools and the theory of elastic and viscoelastic mechanics knowledge study,including: layered elastic system of stress and displacement analysis; Layeredviscoelastic system, the study of the theory of the stress and displacement.Pavement structure under moving load on theoretical issues for further analysis forengineering research, design, construction has important significance in the future.Based on the dynamic response of pavement under the action of the moving vehicle load analysis and research, to reveal the actual work under moving load pavement stresschange rule, in order to provide some reference for future design ideas.
