摘要
针对气囊出运非对称异型沉箱时所遇到的新问题,首先通过对沉箱结构特性及出运时气囊的变形特性分析,选择出合适的平移姿态;然后通过理论及试验证明沉箱顶升前必须对其进行压载;最后,对平移过程气囊的安全性以及沉箱的平稳性进行了分析。通过对非对称异型沉箱的出运技术研究,可以为类似异型沉箱的施工提供借鉴。
To deal with the new problems encountered during the transportation of asymmetrical special shaped caisson with airbags,the appropriate transportation attitude was selected by analyzing the structure characteristic of the caisson and the deformation characteristic of the airbag during shipment firstly;Then,it is proved by theoretical calculation and experiment that the caisson must be ballasted before jacking;Finally,the safety of the airbag and the stability of caisson in the process of translation were analyzed.The research on the transportation technology of asymmetrical special shaped caisson can provide reference for the construction of similar special shaped caissons.
