摘要
广清高速公路扩建工程流溪河大桥主桥预应力混凝土箱梁采用分段切割的方法进行拆除,并利用架桥机将拆除后的箱梁吊运至陆上进行破碎处理。运用有限元结构分析软件ANSYS对不同吊点方式下箱梁应力应变进行分析,从而选取合理的吊点方式,以确保桥梁拆除过程中的安全。
The demolishing of prestressed concrete box girder of Liuxihe Bridge of Guangqing Expressway Extension Project adopts segments cutting, and gantry crane has been used to transport to the land. In the paper, the finite element analysis software ANSYS has been used to analyze the stresses and strains on the prestressed concrete box girder under different hoisting points, so reasonable hoisting point could be selected to guarantee the safety for the bridge cut-demolishing.
