预制短板浮置板轨道减振特性研究
Research on the Damping Characteristic of Precast Short Board Floating Slab Track
摘要
Abstract
Floating slab track is very effective in decreasing the vibration, which has been made full use in urban rail transit. In order to study the dynamic characteristics of floating slab, and compare its damping characteristics with long sleeper buried track, the vibration acceleration data of precast short board floating slab and long sleep-er buried track are collected by field test. The results show that the damping effect of precast short board floating slab track is greater than 20 dB at the section more than 100 Hz in tunnel, and up to 25 dB at the section more than 25 Hz on the ground. It proposes that precast short board floating slab is a highly efficient measure which can achieve the expected damping effect.关键词
