web girder

So corrugated steel web PC box girder bridges can be widely used in earthquake-prone area.

所以，波形钢腹板PC箱梁桥在地震多发区域的应用前景十分广阔。

In these diseases, inclined cracks in the web of box girder are the main, which are likely to affect the normal operation of the bridge, especially reduce the destruction of carrying capacity.

桥梁病害中尤以箱梁腹板斜裂缝的产生和发展较为普遍，而且易影响桥梁的正常运营以致承载能力的破坏。

关于钢箱梁腹板开大孔设计的研究与实践

The results demonstrated that the hydration heat was one of the main reasons which caused the early cracks in the web of box girder.

结果表明：水化热是使箱梁腹板产生早期裂缝的主要原因之一。

Often of fusion adjacent to girder web in the transverse groove welds led to the cracking.

在靠近主梁腹板的横向坡口焊缝处常常出现未熔透而导致裂纹.

Finally, the method of the corrugated high web box girder structure design was introduced, and its use range was broadened, and the technology of construction and design was developed.

最后，引入了波形高腹板组合箱梁的结构设计方法，拓宽了其使用范围，发展了设计和施工技术。

Engineering practice shows that medium-sized span or large span bridge with corrugated steel web PC box girder structure can reduce the weight of the bridge superstructure, so that the seismic excitation effect is significantly reduced and the seismic performance must be improve.

工程实践表明，中、大跨径的桥梁采用波形钢腹板PC箱梁结构能够减轻桥梁上部结构的重量，地震激励作用效果显著降低，抗震性能有一定提高。

So researching and improving web design, exerting material resistance fully, or reducing proportion of no exerting material resistance enough has been used as an important method of solving large span, light weight, saving material in the box steel girder design.

因此，研究、改进腹板设计，充分发挥材料抗力，或尽可能减少未发挥抗力的材料的比重，是推动箱形钢梁朝着大跨、体轻、省料方向发展的途径之一。
