Dynamic response and pore pressure model of the saturated soft clay around the tunnel under vibration loading of Shanghai subway
AbstractThis paper studies the saturated soft clay around the tunnel between Jingansi Station and Jiangsu Station of Shanghai subway line No.2. The continuous dynamic monitoring is conducted by means of embedded earth pressure piezometers and pore piezometers around the tunnel. The response frequency and stress amplitude of the saturated soft clay are studied with the distance from the tunnel due to the subway vibration loading. A formula is proposed for the attenuation of the dynamic pressure response in the soil. Then, based on the continuous field monitored data, and using the laboratory GDS (Global Digital System) test apparatus, the developing law of the pore water pressure of the saturated soft clay around tunnel is explored with the distance. By the GDS test, the model of the increasing pore water pressure of the saturated soft clay is put forward under the vibration loading. It is also amended by field monitored data. Finally the model is obtained. The result offers a valuable reference to the design, construction and the safe operation of the subway tunnel.
