[摘要]在4层框架结构公寓楼的整体平移中,采用带条基整体平移的设计方案,通过间隔轴线的施工方法,完成基础下托换的施工。移动中采用滑动整体平移,通过试验研究,型钢滑块下嵌入聚合物板可以有效的减小摩擦系数,现场顶推测试结果与试验结果相符合。同时为了减小新老地基间不均匀沉降的影响,在新位基础采用平板基础并与原条基进行可靠连接。在移动到位后将行走基础与原条形基础底面间的空隙进行二次浇筑完成上部结构与基础的连接。通过以上的设计与施工保证了公寓楼整体平移工程的顺利完成。

Abstract:A monolithic translation with strip foundation was designed to translate a four-storey frame structure. The underpinning of the foundation was accomplished through interval axes construction method, and the movement way of the monolithic translation is slippage. Based on experimental study, it is found that the formed steel gliding block with polymer plate embed can reduce the friction coefficient effectively, the field push test data match the experimental result well. Flat plate foundation was constructed to connect with the old strip foundation in the new location, in order to minish the effect of asymmetry settlement between the fresh and old foundation. The connection of new foundation and the superstructure was achieved by secondary cast to the interspace between the translation foundation and the underside of the strip foundation when the building was translated to the designed place. Via the above design and construction, the translation project of the apartment block was finished successfully.
Keywords:frame structure; monolithic translation; strip foundation; slip friction, secondary cast
