Article Preview

With the rapid development of industry and transportation, the awareness of environmental problems such as noise pollution and vibration pollution and so on, has led to an increasing interest in methods for noise and vibration isolation. The dynamic mechanical model for forging hammer foundation is analyzed firstly. Through the choice of the scheme of vibration isolation, one vibration isolation trench coupling the piles in rows was design. Grouting piles used as exterior protected structure for vibration isolation trench, which have a role of rigid vibration isolation. Soft material in-filled in the trench, which has a function of flexible isolation, can absorb the residual vibration energy penetrating through the piles in rows. It indicated by the site measurements that the surface waves should be hold back and diffracted effectively by the coupling effect of flexible isolation of the in-filled material and the rigid isolation of piles in rows.
