空沟减隔振对路基本体影响效果的试验研究
Research on the test of the effect of vibration isolation measures of empty groove on the subgrade body
摘要
Abstract
High-speed railway has been increasingly developed because of its obvious superiority in the transportation of our country, but the problem of vibration nuisance has become more and more prominent, which has a significant effect on the surrounding buildings and underground pipelines, living environment and working environment. Based on this, all kinds of vibration isolation measures have appeared relevantly, and it has a certain effect of reducing vibration isolation by the wave reflection, scattering, diffraction. At the same time, the reason why it cannot be ignored is that the wave reflection lead to aggravation of the vibration of high-speed railway roadbed. In view of the problem, this paper analyzed the effect of high speed railway on the subgrade body based on the model test of empty groove reduction and vibration isolation measures in 1 g condition. The results show that empty groove reduction and vibration isolation measures are not only playing their role on the reduction of vibration isolation, but also influencing on the subgrade body of high speed railway; It is not obvious that the change of empty groove width has an effect on the aggravation of vibration of the subgrade body. However, the change of empty groove depth is the major factor on it, with the increase of depth, which is more obvious on the effect of the aggravation of vibration of the basic body of roadbed; So is the change of the distance between empty groove and the subgrade body of high-speed railway.关键词
