超大平面深基坑支撑结构水平体系优化与协同施工技术探析

Horizontal System Optimization and Cooperative Construction Technology of Super Large Plane Deep Foundation Pit Supporting Structure

南京地区地质情况复杂,在业内有地质博物馆之称,长江漫滩地质深基坑施工在业内有独特的研究价值,在基坑面积大、开挖深度深、开挖土方量大、支撑工程量大等因素影响下,如何做好支护设计优化、支撑与土方协同施工、支撑与地下结构协同施工是深基坑工程普遍要面对和解决的难题。

The geological situation in Nanjing is complex,and it is known as a geological museum in the industry.The construction of deep foundation pits in the Yangtze River floodplain geology has unique research value in the industry.Under the influence of factors such as large foundation pit area,deep excavation depth,large excavation earthwork,large support quantities,etc.,how to optimize the support design,coordinate the construction of support and earthwork,and coordinate the construction of support and underground structure is a common problem to be faced and solved by deep foundation pit projects.
