| 先张法张拉台座是先张法预制场重要组成部分，张拉台座设置必需具有足够的强度和稳定性，既安全又经济合理。结合宿淮高速公路泗阳东接线京杭运河大桥引桥空心板梁先张法临时预制场成功实例，介绍预制场总体布局、张拉台座整体设置、张拉台座受力分析、配筋以及运营过程中的质量监控方法。 |
| 英文摘要: |
| The pretension stand is a main part of prestress concrete field. It is required strong strength and stability and be safe and economically reasonable. This paper has taken the pretensioning of plate beam of bridge in Great Canal for instance, and introduced the overall arrangement of the field and the installation of the stand. It also analyzed the stress conditions and distribution bars and introduced the supervision method. |
