摘要
以上海地铁2号线静安寺站-江苏路站区间隧道周围饱和软黏土为研究对象,以现场连续监测资料为基础,利用室内GDS(多功能循环三轴试验系统)试验仪器,探求地铁隧道周围不同深度饱和软黏土的孔隙水压力发展规律。通过室内GDS试验,提出了振动荷载作用下饱和软黏土中孔隙水压力发展模型,并利用现场实测资料对该模型进行修正,最终得到地铁行车荷载作用下饱和软黏土中孔隙水压力发展模型。
The present study is concerned with the saturated soft clay around the running tunnel section from Jingan Temple Station to Jiangsu Station of the Shanghai No.2 subway line. Base on the field measurement data, the characteristics of pore water pressure development in the saturated soft clay around a subway tunnel is studied by using laboratory GDS （Global Digital Systems） . A model for pore water pressure development in saturated soft clay under vibrating load is proposed by using laboratory GDS and field data.
