Ground Movements around Shallow Tunnels in Soft Clay
Prediction of ground movements caused by construction of a shallow tunnel in soft clay is one of the principal problems facing the designer. Both finite element and centrifugal model studies have been undertaken to investigate tunnel deformation behavior in soft clay. The studies were concerned with relating deformations under undrained conditions to temporary support pressures within the tunnels. The finite element analysis was carried out with a program incorporating the Modified Cam-clay model of soil behavior, based on the concepts of Critical State soil mechanics. The combination of results from both the finite element analysis and centrifuge model tests under well defined effective stress conditions suggests a new approach to predicting ground movements associated with construction of shallow tunnels in soft clay.
