| Abstract |
This study aims to scientifically and reasonably assess the damage caused by randomly induced vibrations from construction vehicles driving on gravel roads to existing buildings surrounding the vibration source. The article’s objective is to categorize the gravel road surface into two situations: a flat surface and an uneven surface. Taking into account the uneven characteristics of the two types of gravel road surfaces, a dynamic friction factor is introduced to couple the dynamic friction force and the dynamic vertical force of construction vehicles. Along with the tire elastic roller model, a coupled excitation system between the dynamic load of 1/4 car tires and the gravel road surface is established, utilizing the principle of synergy. Building upon this, and considering the inertia effect of the soil skeleton of the gravel roadbed, a 1/4 car model coupled with the gravel road vibration response model is further developed, providing verification for the solution in this paper. The analysis examines the coupled vibration response characteristics of vehicle-gravel road interaction under random excitation from construction vehicles at different speeds per hour. The results indicate that the horizontal amplitude of the gravel road diminishes rapidly with an increase in the horizontal distance from the vibration source, whereas the vertical amplitude experiences a slower decay with the same increase in horizontal distance from the vibration source. Non-local parameters significantly impact the horizontal amplitude of the gravel road, whereas their effect on the vertical amplitude, though present, can be neglected. The impact of the unevenness coefficient on the amplitude and pore pressure of uneven gravel roads is more pronounced compared to that on even gravel roads. Additionally, the effect of the unevenness coefficient on the amplitude of uneven gravel roads is more substantial than its effect on the pore pressure of such roads. The model presented in this article can serve as a vital theoretical foundation for assessing the damage inflicted on existing structures near vibration sources due to random vibrations generated by construction vehicles traveling on gravel roads. |
