| 摘 要： | 该文通过实际工程对预应力空心板梁梁高进行了分析研究。根据目前运营桥梁的预应力空心板梁检测结果,运营桥梁部分存在因预应力空心板梁梁高过小而引起的梁体破坏现象,这大大地降低了桥梁使用寿命。经对梁高对比验算,从结构受力及经济性等方面,分析了预应力空心板梁梁高的优化对桥梁的重要影响。

| Abstract: | The article analyzes and studies the girder height of pre-stressed hollow plate girder by the practical cases.Based on the inspection testing result of pre-stressed hollow plate girder of bridge under the operation now,the partial bridges under the operation have the failure phenomenon of girder caused by the too small height of pre-stressed hollow plate girder,which greatly reduces the service life of bridge.After the comparison and checking calculation of girder height,the article analyzes the important influence of height optimization of pre-stressed hollow plate girder on the bridges from the structure stress and economy. |
