摘　　要：由于城市更新已进入规模化阶段,随之面临的是整体保留价值不高但对历史环境塑造或承载市民回忆有重要意义的历史建筑的拆留选择。这种情况下,采用对历史建筑有价值的外墙进行修缮保留、内部进行重置建筑功能的“留皮换胆”方式成为城市更新强有力的方式。文中以介绍中海建国东路69地块地下空间开发项目为背景,介绍了既有建筑下方地下空间开发策略,对比分析了成片既有建筑外墙保留条件下,不同开发策略及开挖实施方式的技术、经济性、工期等问题,项目最终采取了原位托换整体逆作法的开发实施方案,为后续类似项目提供借鉴参考。Urban renewal has entered a large-scale phase,facing the challenge of deciding whether to demolish or retain historical buildings with low overall preservation value but significant importance in shaping the historical en-vironment or carrying civic memories.In such cases,a powerful approach to urban renewal is to use the"retain the skin,replace the guts"method,where valuable historical facades are preserved while the internal functions are rede-veloped.This paper uses the underground space development project of the 69 Jianguo East Road,Zhonghai,as a case study to illustrate the strategies for developing underground spaces beneath existing buildings.It compares and analyzes various development strategies and excavation methods under the condition of retaining the facades of large-scale existing buildings,addressing technical,economic,and scheduling issues.The project ultimately adopt-ed the in-situ shoring and reverse construction method for implementation,providing a reference for similar future projects.
