摘　　要：在主体结构已经完成施工,需要再次开挖改造的二次开挖支护的复杂场景,依据现有岩土和结构条件,安全经济地实现建筑功能的转换是本文研究的重点。以马来西亚吉隆坡人民广场为例,阐述了设计思路与理念,利用MIDAS GTS NX有限元软件进行了整体分析,对施工组织顺序进行了详细论证,提出如何克服遇到的技术难题等,为类似工程提供解决思路。充分利用现有的结构体系解决支护问题,需要结构和岩土的充分配合,设计和施工的整体考虑。把原有结构体系作为支护的一部分是合理有效的,是一种高效集约的深基坑支护形式。In the complex scenario of secondary excavation support where the main structure has already been completed and requires further excavation and transformation,the focus of this study is to safely and economically achieve the conversion of building functions based on existing geotechnical and structural conditions.Taking the People's Square in Kuala Lumpur,Malaysia as an example,the design ideas and concepts were elaborated,and an overall analysis was conducted using MIDAS GTS NX finite element software.The construction organization sequence was demonstrated in detail,as well as how to overcome technical difficulties encountered,providing solutions for similar projects.To fully utilize the existing structural system to solve support problems,it is necessary to fully cooperate with the structure and soil,and consider the overall design and construction.It is reasonable and effective to use the original structural system as a part of the support,which is an efficient and intensive new form of deep foundation pit support.
