摘要
针对兰新客专后张法预应力简支箱梁在预应力施工中遇到的问题进行了分析和研究,归纳出后张法预应力简支箱梁施工生产过程中预应力张拉伸长值计算、施加及封锚施工各阶段卡控要点,为今后类似工程施工提供了技术参考。
This paper analyzed and researched the encountered problems of Lanxin passenger special post tensioned pre-stressed concrete simply supported box girder in pre-stressed construction, summed up the ealeulation, summarized the tension value calculation and construction of post tensioned pre-stressed concrete simply supported box girder and the control key points in sealing anchor construction each stage, provided technical reference for future similar engineering construction.
