Abstract: 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, it is identified to be dependable.

Key words: image method, ground loss, grouting capacity, spatial analysis
