【摘要】 桥面铺装层的早期破坏大大的降低了桥梁的使用寿命,针对这一问题,本文作了详细的调查,并在此基础上对铺装层的病害原因进行了分析,同时提出了相应的解决办法。建立了桥面铺装结构的受力模型,对其进行受力分析,并提出了确定铺装层厚度的较为可行的方法。本文基于混凝土铺装层受力及其与主梁共同工作,从结构受力的角度分析研究铺装层结构。选择了具有不同厚度铺装层的单梁进行试验、分析铺装层的受力状态、铺装层厚度对承载力的影响及破坏特征。将铺装层作为结构层研究,以便分析铺装层与主梁共同工作时的受力特点。
【Abstract】 The early destruction of bridge deck pavement greatly reduce the service life of the bridge. In light of this problem, this paper made a careful investigation, on which I analyze the reason causing destruction of the deck pavement and raise one method to solve this problem. This paper establish a model on bearing force of bridge deck pavement to analyze the condition of bearing capacity, and put forward a feasible method for determining the thickness of deck pavement. This article analyze and study the structure of deck pavement from the bearing capacity of structure, which based on the bearing capacity of concrete deck pavement and its working with principal beam. This dissertation select the single beams with different thickness of deck pavement to experiment and analyze the bearing capacity state of deck pavement and the influence of its thickness to carrying capacity and the destruction features. This paper take the deck pavement for structure layer, in order to analyze the features of bearing capacity when plank work with principal beam.
【Key words】 bridge deck pavement; mechanical analysis; rigidity ratio; increasing coefficient of carrying capacity;
