Abstract
The observed pore pressures and deformations induced by an earth balance shield used to construct the Furongjiang sewer tunnel in soft saturated ground in Shanghai, China, are briefly described. Continuous records of immediate surface settlements and ground movements were obtained as the tunnel face approaching and moving away from the observation points. A correlation between resulting heave/settlements and driving force is observed. A finite element technique for predicting these pore pressures and deformations is developed. A comparison is then made between numerical results and the results of field measurements and it is shown that there is encouraging agreement between the calculated and observed response.
