摘要
对某主跨为85 m预应力混凝土连续箱梁桥的合龙段底板崩裂情况进行了调查与分析,运用BAP、ANSYS等有限元软件进行了仿真模拟,分析了箱梁底板混凝土崩裂的机理,并提出了处理类似问题的对策。
The cracking situation of the bottom slab of the closing segment of a continuous prestressed concrete box girder with 85m main span is investigated and analyzed. Using the finite element software , such as BAP and ANSYS , structural simulation is presented. The cracking reason of the bottom slab of box girder is analyzed. Some countermeasures to the similar accidents are proposed .
