Abstract

Abstract

The influence of cover height,face supporting pressure and penetration rate on shield tunneling-induced ground surface settlement was studied with three-dimensinal physical model test.The mechanism of shield tunneling-induced ground surface settlement was analyzed,the ground settlement curves in different conditions were obtained,the influence of cover depth,face supporting pressure and penetration rate of shield tunnel on the surface settlement were discussed,and a newly-modified tunneling-induced ground settlement calculation method was presented.It is revealed that the maximum surface settlement decreases and the transverse settlement trough is widened with the increase of cover height,while the surface settlement increases with the augment of the face supporting pressure.The surface settlement is hardly influenced by the shield penetration,but obviously influenced by boundary soil disturbance induced by shield tunneling.
