The Development of Filled Material for Reduction of Train Vibration

열차 진동 저감을 위한 채움재 개발

Nowadays, the environmental vibration criteria has been severely restricted from the viewpoint of recipient. The vibration created by urban transit systems can be an important source of community discontent, and can have influence on high technology equipments. This has led to a desire of transit system operators to reduce vibration and to minimize community exposure to vibration. Recent research in this area has significantly increased for transit system engineers to reduce vibration. Unlike other material, soil has a complicated characteristic and it is very difficult to prevent vibration from transmitting. Generally, the trench can use to breaking propagation of vibration on passing way but needs much too maintenance. Therefore, the filled materials for trench had successfully developed and the characteristic test for the filled material had conducted during this term. Finally, we had executed analyses of real characteristic through the propagation test of ground vibration.
