桥梁工程预应力箱梁开裂分析及防治对策研究

Crack of Prestressed Box Girder in Bridge Enineering and Prevention Countermeasures

裂缝是预应力箱梁的重大质量问题。引起裂缝的因素很多,也很复杂,主要包括受力和非受力两种。在工程施工中,只要认真分析每一个可能导致裂缝的因素,并采取相应的预防措施,预应力箱梁的施工裂缝就可以得到有效的控制。

Crack is the great quality problem of prestressed box girder. There are many complex causes generating cracks, mainly including force and non-force. In the construction of engineering, cracks of prestressed box girder will be controlled effectively as long as each factor which may induce cracks is analyzed attentively, and corresponding prevention measures are adopted in time.
