文章针对黄土地区陷穴破坏的特点,进行了适当的模拟,建立了陷穴部位板体的微分方程并进行求解;根据交通等级和路面等级进行疲劳和动载修正;结合算例,比较了水泥混凝土路面板底有无陷穴的应力。分析了不同轮载大小、陷穴半径和交通等级下的弯拉应力,及其补强设计所需的配筋量。
In this paper, according to the characteristics of subsidence damage in loess area, the appropriate simulations were carried out, and the differential equations of subsidence plate body were established and solved. The fatigue and dynamic load correction were carried out according to traffic grade and pavement level. Concrete pavement bottom whether the sinking stress. The bending stress under different wheel load, sink radius and traffic grade is analyzed, and the amount of reinforcement required for reinforcement design is analyzed.
