Suppression of Ground Vibration for SSRF Foundation

Abstract:

The electron beam stability is one of the most important requirements for the Shanghai Synchrotron Radiation Facility (SSRF), whose ground vibration is much larger than other light source for softer soil and deeper rock. This paper concentrates on the attenuation of the ground vibration, especially induced by the nearby vehicles. The result indicates that the variation of the ground-vibration amplitude is in a good accordance with the vehicle-number distribution, and the SSRF foundation achieves an obvious attenuation effect since it can attenuating more than 80% vibration induced by the vehicles nearby, which is mainly due to the slab and piles of the foundation. In order to achieve the design criterion, the vehicles with weights equal to or heavier than 10 ton should be prohibited to pass through the nearby roads.
