Trenchless pipe replacement technology by 'EXPANDIT' using hydraulic expansion was established in March, 2006 in Japan, and we received the construction technology certificate of JIWET (Japan Institute of Wastewater Engineering Technology).This trenchless technology of pipe replacement has much effective features. However, many sewer administrators would consider that pipe bursting might damage to adjacent pipes or structures, therefore this pipe replacement technology cannot be used widely for sewer pipes in Japan. In order to solve such problems, we performed experimental pipe bursting operation focused on the ground movement at 6 span's model pipelines in 2005. Consequently, the relation between a distance from existing pipe to measuring point and the amount of ground movement at that point has been understood, and estimation charts of the ground movement were attained. In this paper, we describe the numerical study about the ground movement associated with the amount of radial expansion, while these data following advancing analysis of the data were analyzed in detail, estimation of the ground movement was available. One example of vertical ground movement by pipe bursting operation can be described.
