摘要
预应力混凝土桥梁开裂具有一定的普遍性。针对东明黄河大桥主桥箱梁腹板开裂问题进行了桥梁检测,通过有限元分析和平面杆系模型验算,对箱梁腹板开裂原因进行了分析,提出了针对性的建议。
The pre - stressed concrete bridge cracking represents a general phenomenon. Taking the example of the cracking of box beam web plates in the main structure of Dongming yellow river bridge, this article conducts the bridge inspection, analyzes the cracking causes of the box beam web plates through the analysis of finite elements and the calculation of the plane linkage model, and puts forward some relevant suggestions.
