Wang Min、Zhang Yongtao、Liu Jinghong、Liu Yi、Huang Yue
针对短线预制拼装箱梁几何控制过程中制造及安装阶段的误差控制问题，在分析了误差产生原因的基础上，结合苏通大桥B2标的现场实际情况，介绍以几何控制理论为基础，参数敏感性分析为方法，辅以现代误差分析技术和软件开发技术，实现短线法预制拼装的全过程施工数值化管理与控制。
Focus on error control during fabricating and suspended splicing of box girders with segmentation method. After the analysis of the error reasons, and the combination with practical engineering—Sutong B2, it discussed control method, computing method and sensitive analysis method of linear control of prefabricated pre-stressed continuous beam bridge assembly with short line method.
