Abstract—

A model is developed to identify the main factors and analyze their influence on normal displacements of a roadway surface under the action of a moving load. The model takes into account a multilayer road structure and rheological properties of the ground. The upper layers of asphalt concrete are modeled as a relatively rigid layer, the disconnected layers between the asphalt concrete and the ground are modeled by a base with a Winkler layer, and the soil is considered a viscoelastic half-space. The influence of the sliding velocity, interlayer adhesion, and rheological properties of the ground on surface deformation is analyzed. The effect of reducing maximal surface displacements with increasing sliding velocity is obtained. The developed computational program is designed for use in interpreting measurements of road surface displacements with equipment that provides the surface with a uniform load moving at a constant velocity.

运动载荷对路面变形的模拟

摘要—

建立了一个模型来识别主要因素，并分析它们在移动载荷作用下对巷道表面法向位移的影响。该模型考虑了多层道路结构和地面流变特性。将沥青混凝土的上层建模为相对刚性的层，将沥青混凝土与地面之间的不连接层建模为具有Winkler层的基础，并将土壤视为粘弹性半空间。分析了地面的滑动速度，层间附着力和流变特性对表面变形的影响。获得了随着滑动速度的增加而减小最大表面位移的效果。
