摘要: 上海黄浦路106号“红楼”建于1911年,为三层砖木结构。在其保护性综合改造工程中,面临周边复杂深基坑群同步施工、整体超高位顶升6.55 m以恢复历史风貌以及同步开发地下空间并提升建筑抗震性能的三重挑战。针对上述难题,提出了融合基础托换、变形主动调控、高位同步顶升与隔震增层的成套关键技术:通过可调式主动托换系统,将周边深基坑群施工期间红楼的累积附加变形控制在±5 mm以内;采用“提升+顶升”接力式抬升工艺,实现了6.55 m的超高位顶升,并同步完成300 mm的高位纠倾;增设隔震层显著提升了结构的抗震性能。经全过程三次荷载转换,建筑基础最大倾斜率由初始的9.12‰恢复至2.5‰以下,且未产生新增结构性裂缝。该工程在紧邻深基坑群同步施工的环境下实现了上海市优秀历史建筑的原位保护、顶升增层与功能提升,创造了近代优秀历史建筑整体顶升高度之最。Abstract: The Red Mansion at No. 106 Huangpu Road, Shanghai, was constructed in 1911. It is a three-story brick-wood structure. In its comprehensive protective renovation project, three major challenges were encountered: the simultaneous construction of a complex group of adjacent deep foundation pits, the overall ultra-high jacking by 6.55 m to restore its historical appearance, and the synchronous development of underground space together with the improvement of the building’s seismic performance. To address these challenges, a complete set of key techniques was proposed, integrating underpinning, active deformation control, synchronous high-position jacking, and seismic isolation with story addition. Using an adjustable active underpinning system, the cumulative additional deformation of the Red Mansion during the construction of the surrounding deep foundation pits was controlled within ±5 mm. A relay lifting technique combining "lifting + jacking" was adopted to achieve the ultra-high jacking of 6.55 m, along with the simultaneous high-position rectification of 300 mm. The addition of a seismic isolation layer significantly enhanced the structural seismic performance. After three rounds of whole-process load transfer, the maximum inclination ratio of the building foundation was reduced from the initial 9.12‰ to below 2.5‰, with no new structural cracks generated. This project realized the in-situ preservation, jacking with story addition, and functional upgrading of an outstanding historical building in Shanghai under the condition of simultaneous construction adjacent to a group of deep foundation pits, setting a record for the highest overall jacking height of modern outstanding historical buildings in China.
