| Abstract: | The ground surface settlement caused by tunnel shield construction is calculated by the empirical formula.MIDAS(GTS) is applied to the numerical simulation during the construction stage,and the value of simulation is compared with the calculated value and the measured value.The rationality of the empirical formula and the numerical simulation is verified.Thus the scope of transverse of ground settlement due to the shield construction is presented and it has guiding significance for the protection of surroun... |
