复杂环境下群坑支护设计

Design of group excavation support structure under complex environment condition

以上海广富林遗址公园2-2休闲商业地块基坑围护设计为背景,通过对地质条件、周围环境及基坑本身特点的分析,结合业主对地块开发的需求,统筹考虑了片区的基坑围护形式,通过围护体的相互利用,不仅节约了投资,其积累的技术经验也可为类似的群坑支护设计提供一定的参考。

This paper takes the design of the excavation of 2-2 leisure commercial site of Shanghai Guangfulin Relics Park as the background.Through the analysis of geological conditions,the surroundings around excavations and the characteristics of the excavation itself,based on the owner’s demand for developing the block,the overall consideration of the form of the excavation support structure in the area,through the mutual utilization of support structures,not only saves the investment,but also provides some references for the similar cases of group excavation engineering design by the accumulated technical experiences.
