摘要
分析水泥混凝土桥面防水层参数对层间稳定性的影响,采用有限单元法,建立模型,选取防水层厚度和模量两个参数,分别研究其对防水层与铺装层剪应力和防水层与桥面板间应力的影响。研究表明,相对防水层与桥面板或铺装层间的应力,防水层参数的变化对防水层与桥面板间的应力较为敏感。其中,防水层模量对防水层与上、下层间的应力影响较大,最大影响幅度达70%。
In order to analyze the influence of parameters of waterproof layer of cement concrete bridge deck on interlayer stability, the finite element method was used to establish a model, and the thickness and modulus of waterproof layer were selected to study their influence on shear stress between waterproof layer and pavement layer and stress measurement between waterproof layer and bridge deck. The analysis shows that the modulus of waterproof layer has a great influence on the stress between layers, and the stress between waterproof layer and bridge deck is relatively sensitive.
