Abstract: In shallow shield construction, the interaction of double track tunnels makes the surface settlement complex and difficult to calculate accurately. To explore the distribution of ground deformation and the evolution law of settlement, an improved three-dimensional Peck formula was established. The total settlement caused by shield tunnel construction was calculated by considering the axis distance S of double track tunnel and the distance K in front of and behind the excavation face; relying on Nanchang Rail Transit Line 1 project, ABAQUS finite element method is used to simulate the construction process of double line shield, draw the settlement curve, analyze the influence of different working conditions on the surface settlement, determine the zoning control standard, and compare the numerical simulation results with the measured settlement data of shallow buried tunnel engineering. The research shows that the settlement limit of the core influence area (|x|≤ 1.5D) is 15 mm, and the settlement limit of the secondary influence area (1.5D ＜ |x|≤ 2.5D) is 10 mm. The settlement curve obtained by simulation is consistent with the settlement curve of the actual engineering case, and the relative error between the predicted settlement and the actual settlement is only about 3%.
