摘要
针对影响桥面铺装层间界面剪切特性的因素开展了试验研究和数值模拟研究。结果表明:桥面铺装层间界面的剪切强度随试验温度的升高而降低,随加载速率的增大而增大;当调平层表面构造深度在6 mm左右时,铺装层间界面的抗剪性能能够最大限度地予以发挥;沥青混凝土面层的厚度和防水粘结层的弹性模量对铺装层间界面的抗剪强度影响较大,而沥青混凝土的弹性模量和防水粘结层的厚度对抗剪强度的影响则可以忽略。
The article has studied the influential factors for the shear characteristics of the bridge deck interlayer through laboratory test and numerical analysis. The result indicates that the shearing strength reduces as the experimental temperature elevates, goes up with the load speed increases; The shear characteristics of the bridge deck interlayer displays most as the deck concrete surface＇ s structure depth reach about 6mm ; the asphalt concrete＇ s thickness and the waterproof adhesive layer modulus has a great influence on the shear strength, but the influence of the modulus of asphalt and the thickness of the waterproof adhesive on the shear strength of the bridge deck interlayer can be neglected.
