江滩软弱地基区地下停车场围护结构设计及施工探讨

Exploration on the Design and Construction of Enclosure Structure of Underground Parking Lot in Soft Foundation Area of Riverbank

为节约用地、满足城市规划需要,越来越多的地铁停车场设计为地下式。南京地铁鱼嘴停车场位于长江江滩区,地基软弱,淤泥层厚,分布着大量流砂层,地下水位较高。停车场的围护结构设计标准高,施工难度大。本文详细论述了鱼嘴停车场围护结构的设计形式、施工方法等,以期对软弱地基区地下停车场设计、施工提供参考。

In order to save land and meet the needs of urban planning, more and more underground parking lots are designed. Yuzui parking lot of Nanjing Metro is located in the Yangtze River beach area, with weak foundation, thick silt layer, large distribution of quicksand layer and high groundwater level. The design standard of enclosure structure is high and the construction is difficult. This paper describes in detail the design form and construction method of the enclosure structure of Yuzui parking lot, which can provide a reference for the design and construction of underground parking lot in soft foundation area.
