以湖南省某高速公路水泥混凝土桥桥面层间处治为实际研究背景,根据工程不同桥型,应用有限元方法进行实体建模,分析防水层最大应力位置以及影响因素,计算层间最大剪应力大小,初步提出层间剪切强度、黏结强度控制指标,为深入进行湖南省娄新高速公路水泥混凝土桥桥面层间处治研究,提供理论依据。
Based on the actual research background of cement concrete bridge decks in a highway in Hunan Province, according to the different bridge types of engineering, solid modeling is carried out by finite element method. The maximum stress position and influencing factors of waterproof layer are analyzed. The maximum interlaminar shear stress Size, preliminary proposed interlaminar shear strength, bond strength control index, in-depth Hunan Louxing Expressway cement concrete bridge deck between the study to provide a theoretical basis.
