根据农村公路实际情况和试验路段条件,利用有限元法,计算分析了路面板平面尺寸对荷载应力的影响,确定了农村公路薄层水泥混凝土路面板的合理平面尺寸。研究表明,农村公路薄层水泥混凝土路面板的平面尺寸对板底最大拉应力有明显影响。利用荷载疲劳应力确定路面板的平面尺寸,与试验路观测分析的结果一致。 According to the actual conditions of rural roads and the conditions of the test road sections, the influence of the plane dimensions of the pavement slab on the load stress is calculated and analyzed by using the finite element method. The reasonable plan dimensions of the thin-walled concrete pavement slab of rural roads are determined. The research shows that the plane size of the thin-wall cement concrete pavement slab in rural road has obvious influence on the maximum tensile stress of the slab. The load fatigue stress was used to determine the plane dimensions of the pavement slabs, which was in good agreement with the experimental observations.
