Abstract

Back-fill grouting model tests have been carried out and the behavior of back-fill grouting of shield driven tunnel is discussed in this paper. Back-fill grouting of shield driven tunnel is significant for not only surrounding ground but also acting load on tunnel. Ground displacement and acting pressure on the tunnel model were measured during back-fill grouting. Some durability tests for grout material have also been done. The differences of the injection pressure and stiffness of surrounding ground varied the acting pressure on the tunnel model and ground displacement.
