无锡航站楼二期工程基础根据施工要求、江苏省规定,通过技术、经济分析后,选用预应力管桩作为抗压桩和抗水平力桩,预制钢筋混凝土方桩为抗拔桩,新老航站楼连接处以及航站楼与站前雨篷连接处采用钻孔灌注桩。文章重点介绍根据作用荷载及施工条件,进行桩基设计,选用不同的桩型、桩径及桩长,做到经济合理,并对预应力管桩作为抗拔桩进行了各项验算。建议尽快出台相关管桩连接接头方式,方便设计与施工,节省工程造价。
Based on the construction requirements, Jiangsu Province stipulates that prestressed pipe piles should be selected as anti-pressure piles and anti-horizontal piles after technical and economic analysis. Precast reinforced concrete square piles shall be anti-pull piles and new and old Terminal connection and the terminal and the station before the awning connection with bored piles. The article focuses on the basis of the role of load and construction conditions, the design of the pile, the use of different pile type, pile diameter and pile length, so that economic and reasonable, and prestressed pipe pile as a pile uplift the various checks. Proposed as soon as possible the introduction of pipe joints connected to facilitate the design and construction, saving construction costs.
