DESIGN AND APPLICATION OF MONOLITHIC MOVEMENT OF THE HISTORICAL BUILDING JINAN CONVENT

摘要: 济南市修女楼为二层加阁楼的砖木结构建筑,建于1893年,为历史性建筑。2020年6月采用自行式模块运输车对其进行了迁移,是当时国内采用拖车移位的最大的砌体结构建筑物。着重对移位方案、移位前对建筑物的维修和加固、车辆布置、托换结构设计及基础和地下室设计等进行介绍。对托换结构按车辆与上部结构协同受力及分别受力计算进行了分析,得出了拖车移位的砌体结构,其车架受力可按倒梁法计算,建筑物轮廓范围内托换结构可按支承车辆的底框结构进行设计,外挑于建筑物外的托换结构需要按悬挑构件进行加强。根据地下室的逆作法施工要求,宜采用桩柱一体的设计。Abstract: The Jinan convent, built in 1983, is a historical building of two-story masonry-timber structure with a loft.It was monolithiclly moved in June 2020 by Self-Propelled Modular Trailers. and which was the largest masonry structure building moved by trailers in China at that time. The determination of the movement scheme for the project, the maintance reinforcement design before the movement, the trailers layout, the underpinning structure design, and the foundation and basement design were introduced. Analysis on the force calculation of underpinning structure was conducted according to joint or separated force of the trailers and the structure. The force on the trailer beams could be calculated according to the inverted beam method. The underpinning structure within the building outline could be designed according to the masonry structure with bottom frames of supports or trailers. The underpinning structure overhanging outside the building outline needed to be strengthened as cantilever beams. According to the requirements of the reverse construction method for underground buildings, the underground structure was designed to integrate the piles and columns.
