中文摘要：

以上海地铁二号线静安寺站-江苏路站区间隧道周围饱和软黏土为研究对象，通过对隧道周围不同位置、不同深度土体中预埋土压力盒和孔压计，进行现场连续动态监测，对地铁振动荷载作用下饱和软黏土的响应频率、土体响应应力幅值随距离地铁隧道远近以及土体响应应力幅值随深度的变化规律进行研究，并提出了土体动力响应衰减计算公式，利用该式可以计算出地铁列车经过时的影响范围及其动力响应值的大小，可以预测与估算地铁列车振动荷载对周围建筑物的影响情况，为地铁设计、施工以及安全运营提供有价值的参考。

英文摘要：

The subject of concern is the saturated soft clay around the running tunnel between Jingan Temple Station and Jiangsu Station of the Shanghai No.2 subway line. Continuous dynamic monitoring is conducted by means of embedded soil pressure cells and pore-water pressure meters around the tunnel. The variations of frequency and amplitude of pressure with the distance from the tunnel due to subway vibration load are studied. A formula is proposed for the attenuation of the dynamic pressure response in the soil. The range of influence and the amplitude of dynamic response are calculated. The influence on the surrounding buildings by subway vibration load is predicted.
