Research of Effects and Control Methods of Ancient Stone Pagoda Vibration Caused by Shield Tunnel Construction

The amount of underground engineering increases steadily in large and medium-sized cities as unban construction develops rapidly. Then surrounding effect caused by tunneling is of great concern, especially the effect to important building and vibration-sensitive buildings. For tunneling engineering construction effect of Hangzhou Zijiang road to Hangzhou white pagoda, comprehensive numerical simulated analyses were conducted. Three dimensional Foundation-tunnel-pagoda FEM model has established. Effect caused by tunneling engineering construction to Hangzhou white pagoda was calculated with ABAQUS software. The simulation results showed that the calculated vibration value has gone beyond the limitation of standard regulation value without protective measures. It does not satisfy isolative vibration requirement under isolation trench of superficial layer (8.2 m). And it can satisfy the requirement under isolation trench of medium layer (17.45 m) and better satisfies the requirement under isolation trench of deep layer (32.7 m).
