Abstract: The ground subsidence as well as the disturbance of soil around the large diameter pipe excavation might be induced by the pipe jacking construction. This paper provides a review of the development of the methods that predicting the ground subsidence and a review of the ground subsidence mechanism. The ground subsidence methods can be categorized as: empirical, theoretical, numerical and statistical from observed data. Current research topics and their solutions are also discussed in the paper.
