摘要 高速铁路的桥梁工程建设,为节约运输费用,并满足施工进度和工期要求,需在现场修建预制梁场,集中预制箱梁,采用架桥机架设。如何使梁场布设合理,又节约投资,此文通过建立数学模型来论证预制梁场的布设方案,使架梁工期最短,并通过某工程实例来验证所述方案的可行性。 In order to save transportation cost and meet the construction schedule, the prefabricated yard of box girder need to be built for the construction of high - speed railway bridge. And the box girder is precast and erected with bridge girder erection machine. The way how to make the layout of prefabricated yard reasonable and save investment is analyzed. The mathematical model is established to demonstrate the layout of precast beam field to shorten the period of beam erection. And an engineering example is given to verify the feasibility of the proposed scheme.
