摘      要：With the increasing demand for transportation infrastructure,the construction of urban tunnel systems linking different areas is *** deformation and the failure process during a tunnel excavation are essential concerns for geotechnical ***,few studies have systematically investigated the effect of the ground loss ratio on tunnel deformation and the inequality between the ground loss ratio and the volume of the settlement *** experimental study using the transparent soil testing technique is performed herein for better visualization and digitization *** three dimensional vertical and horizontal deformation patterns of a single tunnel are investigated for both the surface and the stratum right below considering different ground loss *** relationship among the empirical constant of the settlement trough width,buried depth,depth-diameter ratio,and ground loss ratio is presented.
