饱和软黏土地基堆载预压固结设计实例简述

Brief description of piled-load preloading consolidation design of saturated soft clay foundation

针对上海某货站工程地处东南沿海地区,浅部地基土存在较厚饱和软弱黏土层,且室内外地坪堆货区荷载较大的特点,为消除工后使用期内产生的较大沉降和沉降差,采取堆载预压法对软弱地基进行了排水固结处理,从而为类似的工程设计积累经验。

Aiming at the characteristic of a freight station in Shanghai located in southeast coastal area,thicker saturated soft clay layer existing in the superficial foundation soil,and interior and exterior floor heaped loads being big,the piled-load preloading method was adopted to treat the drainage consolidation of soft foundation to eliminate the larger settlemeot and settlement difference caused in useful life after construction,so as to accumulate experience for similar engineering design.
