摘要
结合太原市某变电站饱和粉土地基处理中出现的地基下沉现象,在采用碎石桩结合堆载预压进行地基处理后,通过埋设孔隙水压力传感器,监测超孔隙水压力的变化情况,由此计算出地基的固结度,进而推测出地基的后续沉降。其固结度结果与观测的基础沉降数据也比较吻合。
What is concerned in this paper is the phenomenon of ground subsidence in the treatment of saturated silt ground of a transformer substation in Taiyuan.After the constructions of gravel pile and preloading,according to the change of excess pore water pressure from embedded pore water pressure sensor,the degree of consolidation of the foundation is calculated and then Infer the subsequent settlement.The result of consolidation degree also is consistent with observation data of foundation settlement.
