摘　　要：准确细致的施工过程仿真计算是大跨度混凝土斜拉桥施工监控的关键问题之一,它可以为大桥各阶段的施工监控提供理论依据。根据崖门大桥主梁施工工艺的特点,建立了牵索挂篮施工模拟计算的流程,并对牵索方案的选择以及主梁立模标高的确定等问题进行了探讨。在此基础上,给出了崖门大桥主梁的施工流程及其计算结果。The correct and careful simulation calculation for construction process is one of the important concerns for construction control of longspan concrete cablestayed bridges and can provide theoretic bases for the construction control at various stages of the bridges. In this paper, according to the construction technique features of the main girder of Yamen Bridge, the process of construction with the guyed traveler is established and the issues regarding the selection of the guy construction schemes and determination of the elevation of the girder formwork are discussed, and the construction process and calculation results of Yamen Bridge are presented as well.
