Shield tunneling causes movements of the soil around the tunnel
so estimating potential soil movement is very important to control soil movement amount and protect existed construction foundation and underground pipelines. Soil displacements are induced by ground loss and are affected greatly by grouting amount. According to the regularities of distribution of ground loss and grouting amount
the paper initiates spatial analysis of soil displacements and stresses during shield tunneling by using image theory. Comparing with the observed results of Tianjin metro project
