| Abstract |
By virtue of its scientific and practicality, the coupled vibration theory of roller-roadbed has become one of the key factors indispensable for assessing the compaction quality of roadbed. Currently, the coupled roller-roadbed vibration model for evaluating the performance of roadbed compaction by rollers can only assess the coupled vibration response between rollers and roadbeds through
indirect parameters, which still cannot directly and accurately reflect the coupled vibration response
problem between rollers and roadbeds. Therefore, the main research objective of this manuscript is to
propose a novel method to assess the vibration-induced engineering disaster problem during roadbed
compaction. By introducing the dynamic friction effect, the method proposes a new coupled roller-roadbed vibration response calculation model under the consideration of the influence of the dynamic
friction effect, and establishes the coupling relationship between the coupled roller-roadbed vibration
system and the dynamic modulus of the soil layer pressure of the roadbed and the traveling speed of
the roller during the compaction process. It is found that the computational model can more accurately simulate the coupled vibration response of the roller and roadbed under the dynamic friction
effect. Meanwhile, the analytical results show that compared with the dynamic friction coefficient, the
contribution of the dynamic friction coefficient to the surface amplitude is much more than the amplitude itself. The nominal amplitude and the friction coefficient mainly affect the surface amplitude
during the compaction of the roadbed by the road roller, while the effect on the frequency distribution
is not obvious. By analyzing the coupled vibration response of the roller and the roadbed in the process
of compaction of the soil layer by the roller, the attenuation degree of vibration in the process of compaction of the roadbed by the roller is scientifically evaluated, and the theoretical basis is provided for
the evaluation of the vibration-induced engineering disaster in the process of compaction of the road-bed. |
