摘　　要：目的 探究重载交通条件下钢波纹管涵对沥青路面的变形影响,提高埋设钢波纹管涵沥青路面的寿命。方法 以计算机科学、道路工程等理论为基础,借助Midas GTS NX软件建立三维地层结构模型,对不同荷载下埋设钢波纹管涵的前、后多种工况进行模拟分析,探究荷载与钢波纹管、沥青路面不同方向变形之间的关系。结果 钢波纹管的埋设可以有效扩散土体中的应力,减少车辆荷载带给路面各结构层的沉降变形;双钢波纹管在荷载作用点处的变形较大,相邻管涵的变形较小,上半管对应力的承受程度要远大于下半管;得到了钢波纹管变形“飞鸽”模型。结论 不同荷载作用下,轴载的增大会减弱钢波纹管的应力扩散效果;笔者构建了不同荷载与路面结构层变形的关系模型,可为铺设钢波纹管涵沥青路面的病害防治提供数据支持。The deformation of steel corrugated pipe culvert under heavy traffic conditions affects the deformation law of asphalt pavement.In order to improve the service life of buried steel corrugated pipe culvert asphalt pavement, based on the theory of computer science and road engineering, a three-dimensional stratum structure model is established with the help of MIDAS GTS NX software to simulate and analyze various working conditions of buried steel corrugated pipe culvert under different loads.The relationship between load and deformation of steel bellows and asphalt pavement in different directions is explored.The results show that the embedding of steel bellows can effectively diffuse the stress in the soil and reduce the settlement deformation of each structural layer brought by vehicle load;The deformation of double steel bellows at the load point is larger than that of adjacent pipe culverts, and the stress bearing degree of the upper half pipe is much greater than that of the lower half pipe;Under different loads, the increase of axle load will weaken the stress diffusion effect of steel bellows, and the relationship model between different loads and pavement structural layer deformation is constructed, which provides data support for disease prevention of asphalt pavement with steel bellows culvert.
