Abstract

Ground vibration is a key issue for the Shanghai Synchrotron Radiation Facility (SSRF), which is a third-generation light source under commissioning. However, the ground vibration of the SSRF is much larger than other light sources for relatively softer soil and deeper bedrock. More than 1000 piles with 0.6 m diameter down to 48 m underground, and slabs of 1450 mm thickness for the storage ring tunnel and the experiment hall, have been used to attenuate the ground vibration. Measurement results show that these piles and slab have obvious attenuation effect for the vibration induced by nearby vehicles and air conditioners. The coherences with respect to different distances are also carried out.
