An Application of Micropile to Reehrain the Settlement of Structure on the Ground Surface Caused by Shield Tall Void

[ 초 록 ]

In soft ground tunneling, shield method is very good for safety of neighboring structures. Although shield tunnel method has the merits to minimize the deformation of ground around tunnel, ground deformations occured until the material grouted in tail void hardens are inevitable.In this study, the effects of micropile used as one method to restrain the settlement of neighboring structures by the tail void are studied by laboratory model tests. As a basic test result, the effective direction of micropile and the restraint rate of settlement by micropile reinforcement are known.
