摘要：
New tunneling close to an existing tunnel may damage the existing tunnel lining if no appropriate measures are taken during construction. A series of centrifuge tunnel models with various cover-to-diameter ratios (CID = 1, 2, and 3) both in the plane strain condition and in the 3-dimensional condition were performed in an acceleration of 100g to investigate the distributions of earth pressure around tunnels and the bending moment on lining during the tail voids closures caused by nearby new tunneling. The failure mechanism and load mechanism are demonstrated in the paper.
