摘要
高大钢管梁柱式现浇支架是一种体量相对较大、经济性相对较差、危险性较大的施工方法.但在山区陡坡地段,由于各方面施工条件的限制,此种施工方法又不得不被采用.黑山南北高速公路四分部UVAC2桥梁现浇支架由于地形复杂,为典型的陡坡高大现浇支架,对此类山区支架结构的支墩立柱、平联、基础的设计思路和方法以及施工控制要点进行阐述,为后续类似工程提供借鉴.
Abstract
High and large steel beam-column cast-in-place supports are a relatively large-volume,relatively not economical and dangerous construction method.However,in the steep slopes of mountainous areas,due to various construction conditions limitations,this structure type has to be adopted.Taking the UVAC2 cast-in-place bridge scaffold at the Part 4 of the Montenegro Bar-Bojlare as an example,here are described the design,calculation and construction control of such structure.
