摘要:
采用弹性层状体系的力学模型,利用有限元法和模型试验方法对由于小型构造物存在而导致的路表拉应力进行了详细分析并研究了其结构性能.结果表明:由于构造物存在而引起的路表拉应力受构造物顶部填土高度以及基层厚度的影响较大,而构造物两侧回填压实较为困难,则是含构造物路面产生病害的主要原因.
Abstract:

Using the mechanical model of elastic layered system, the tensile stress of the road surface caused by the existence of small structures was analyzed in detail by finite element method and model test method, and its structural properties were studied. The results show that the tensile stress of the road surface caused by the existence of the structure is greatly affected by the top fill height and the thickness of the base layer of the structure, and the backfill compaction on both sides of the structure is more difficult, which is the main cause of disease in the pavement containing the structure.
