摘要 桥头搭板是一端简支在桥台上,另一端搁置在桥头引道路基或者路面结构材料上的钢筋混凝土板。拟对高速公路通道桥两端桥头搭板进行了试验与研究,其中静载试验荷载作用下搭板底面对路基产生压力大小,以便判断是否有脱空即脱空位置,动载试验内容动载试验是对通道桥头搭板的动力特性以及汽车荷载作用下的动力响应进行试验研究,并评价行车舒适性。本文通过对高速公路桥头搭板静载和动载试验进行研究,对桥头搭板的结构形式的合理性,以及试验桥头的行车舒适性进行分析。 Bridge head bump is an armored concrete slabone, whose one end is simply supported on the abutment and the other end is laid up bridgehead to approach road subgrade or to pavement structure material.The test and research of bridge head bump between highways Channel Bridge. In order to judge whether there are gapped location or not, a static loading test was used. The test generates pressure via bump undersurface to subgrade. Dynamic loading test was used to study the dynamic response under the dynamic property of bridge head bump and the vehicle load and to evaluate roadability. The paper analyzes the rationality of the bridge head bump type of construction and roadability by mean of static loading test and dynamic loading test.
