铁路大型箱梁预制场规划与布置 （中铁十二局集团第四工程有限公司, 西安 710021） 摘要：随着高速铁路建设的发展，双线900吨预应力整孔箱梁对制梁场的标准化、工厂化建设要求也越来越高。因此在梁场建设中必须坚持“整体设计、系统建设、优质高效、一次建成”的方针，坚持系统性、先进性、经济性、合理性与实用性相结合的原则，达到“一流的设计、一流的工程、一流的技术装备”的建设目标；本文结合京沪高铁及大西客专新制梁场的建设经验，从梁场选址、梁场规划布置设计和制梁设备的配备等方面对大型箱梁预制场的建设加以介绍，以供参考。 关键词：高速铁路；客运专线；大型箱梁预制场；规划与布置 Planning and Layout of Precasting Yard for Large-scale Railway Box Girder GAO Jun (The 4th Engineering Co., Ltd. of China Railway 12th Bureau Group, Xi’an 710021, China) Abstract: With the development of high-speed railway in our country, a higher standard is required for the construction of normalized and industrialized precasting yard to cast 900 t prestressed whole-span box girder for a double line railway. Therefore, the construction of girder yard must stick to the policy of “integral design, systematical construction, high-quality and high efficiency and fulfilling it with once-through construction” and the principle of “integrating systematicness, advancement, economy, rationality and practicality” to reach the construction target of “first-class design, first-class engineering and first-class technical equipment”. Combined with the construction experience of girder yard for Beijing-Shanghai high-speed railway and Datong-Xi’an Passenger Dedicated Line, The paper introduces the construction of large-scale box girder precasting yard in respect of construction experience, site selection, planning , layout and design of girder yard and allocation of girder precasting equipment, which is expected to be reference for other similar projects.
