混凝土路面临界荷位分析

A Study of Critical Loading Position for Concrete Pavements

本文分析比较了混凝土路面板在纵边和横边处的应力状况,并结合轮迹横向分布情况分析比较了不同荷位时板的疲劳损坏。在此基础上,为采用不同设计标准的各设计方法提出了合理选取临界荷位的建议。

The adoption of critical loading position for concrete pavements depends upon the stress regime induced, as well as the fatigue damage incurred by the applied loads. This paper presents an analysis of the critical loading position, by comparing the maximum stresses and fatigue damage along the longintudinal and transverse edge of concrete slabs. Suggestions on selecting critical loading position are offered for developing concrete pavement design procedure with various design criteria.
