| Abstract: | In order to investigate the influence of different lateral-stress coefficient and non-synchronously on two tunnels,a series of calculations and analyses are carried out by using the analysis of FEM.Through the in-situ dynamic measurements,the author proved the results of FEM.Through these analysis,the result shows that the larger lateral-stress coefficient,the larger influence. |
