摘要
由于工业上特种重载运输的需求,以及桥梁结构的承载力不足的缺陷,目前重载运输途中往往有需要加固的桥梁。不同于目前多采用标准公路等级荷载作为验算荷载,该文采用特种荷载中的挂车荷载进行通过性验算。首先,以一个运输途经的桥梁加固为案例,详细分析了桥梁加固的流程,然后采用有限元模型对桥梁加固前后的承载力进行了分析,最后对运输挂车的通过性进行了验算。
Due to the demand for special heavy-duty transportation in the industry and the lack of bearing capacity of the bridge structure,many of the bridges need to be reinforced.In this paper,a bridge reinforcement method is taken as a case to analyze the bridge reinforcement process in detail,including the bearing capacity analysis before and after the bridge reinforcement,the possibility check of the transport trailer,etc.The analysis process is detailed and the results are reliable.
