本文提出了一个多层弹性体系路面位移和应力的简化计算方法,这个方法在进行层次当量换算时,考虑了荷载随深度的扩散影响;为了路面结构设计的需要,在计算厚度时引进了一个结构系数。如此,使得简化法的计算结果与多层体系精确解十分接近。 这个方法与国内现有的等效层法比较,在一定范围内具有精度较高、适用范围较广的优点;与国外类似方法比较(如修正Odemack法),具有概念清楚、计算简便、容易掌握的优点。
This paper proposes a simplified calculation method for the displacement and stress of a multi-layered elastic system pavement. This method considers the influence of the load-diffusion with the depth when performing the equivalent-equivalent conversion. In order to meet the requirements of the pavement structure design, a structure is introduced when calculating the thickness. coefficient. In this way, the calculation result of the simplified method is very close to the exact solution of the multi-layer system. Compared with the existing equivalent layer method in China, this method has the advantages of higher accuracy and broader application range within a certain range; compared with similar foreign methods (such as the modified Odemack method), it has a clear concept, easy calculation, and easy to grasp. The advantages.
