摘　　要：针对先张法预应力混凝土空心梁底板张拉施工工艺后出现纵向裂纹的现象进行分析,采用有限元软件AN-SY S仿真技术,从理论上分析了裂纹产生的原因,提出了切实可行的解决办法。The fact that many cracks appear on the bottom plate of the pretensioned prestressing concrete hollow beam after it was constructed was studied. The reasons of cracking were simulation analyzed by using finite element software ANSYS. And the solutions were put forward.

关 键 词：先张法预应力空心梁 裂纹 有限元分析
