英文摘要	The aim of this paper is to analyze and predict the construction settlement of shield tunnel in soft-soil area. Using the shield tunnel excavation gap parameters, by introducing the width correction coefficient b of the settlement trough, the analytical solution of shield tunnel construction settlement was obtained based on the Peck formula. Different buried depth ratios, unified focus spacing d and correction coefficient b were selected to analyze the ground settlement of tunnel construction. The results show that for shallow buried tunnel, the maximum settlement at different depths of the stratum shows a linear increase trend. For deep buried tunnel, with the deepening of depth, the maximum stratum settlement increases firstly linearly and then decreases gradually. Under the same buried depth, with the increase of the focus spacing ratio d/Dm, the settlement of the stratum increases gradually for strata with different hardnesses. Combined with engineering examples, the reliability of the proposed settlement prediction method is verified by the maximum ground settlement Smax(z) and the settlement curve S(x,z).
