项目摘要

This research project first has dealt with the computer simulation of the high-speed train induced ground vibration. The track loading is assumed by a set of harmonio moving function of different frequencies in view of a train geometry (axle distances of a car and connection of cars). Besides, sleeper distances and other vibration factors involved are of essence for the periodicity of alongside vibration so that an inverse analysis is introduced of the measured data for the Shinkansen running. The 2.5 dimensional FEM-BEM method developed by the authors is used for the analysis. Thus simulated ground vibration results in a good prediction for the attenuation of alongside vibration acceleration value (VAL).Next, lineside ground vibrations induced by high-speed trains and the mitigation measure are discussed from the computer simulation. The simulated ground vibration due to a train system of axle loads is interpreted from the knowledge of wave propagation in layered soil. The vibration reduction rate by the proposed X-WIB based on thus obtained information is demonstrated for the wave field before and after the installation.Thirdly, a field construction of a WIB is conduced by a set of soil column construction and the effect of the vibration reduction is measured. The corresponding computer simulation is also carried out in order to validate the aforementioned results for the Shinkansen vibration simulation and the reduction effect by the WIB procedure.
本课题首先对高速列车引起的地面振动进行了计算机仿真。考虑列车几何形状(车辆的轴距和汽车的连接),轨道载荷由一组不同频率的谐波移动函数来假设。此外,轨枕间距等振动因素对列车横向振动的周期性也有重要影响,因此,对新干线列车横向振动的实测数据进行了反分析。采用作者提出的2.5维有限元-边界元法进行分析。因此,模拟的地面振动对列车横向振动加速度值(瓦尔)的衰减有很好的预测作用。其次,通过计算机模拟,讨论了高速列车引起的线路侧地面振动及其抑制措施。从层状土中波的传播理论出发,对列车轴载系统引起的模拟地面振动进行了解释。根据所获得的信息,对安装前后的波场进行了振动衰减率的验证。第三,通过一组土柱结构进行了振动衰减器的现场施工,并对振动衰减效果进行了测量。为了验证新干线振动模拟的上述结果和WIB程序的减振效果,还进行了相应的计算机模拟。
