某国际旅游度假区周边开发受轨道交通振动影响的方案优化

Optimization of an International Tourism Resort Zone Development Affected by Metro Vibration

以某国际旅游度假区周边开发项目为例,分析预测了其地下穿行的轨道交通线路运营对环境振动的影响。本案轨道交通线路设计时速为160 km/h,远高于国内一般轨道交通线路运行时速。由于目前该轨道交通尚未进行建设,无法直接获取其实际的振动影响和传播衰减规律,因此通过类比振源的实际测试结果,结合半经验模型法进行分析预测,最终从减振降噪的角度对园区开发设计方案优化对策。

The impact of vibration caused by the metro around an international tourism resort zone has been studied and predicted in this paper.The speed of the metro was about 160 km/h which was much higher than the general metro in China.The impact of the vibration and attenuation law of vibration propagation can't be directly achieved because the metro has not been constructed yet.The actual vibrat ion of the metro nearby and the semi-empirical model have been applied to analyze the impact.The optimization of vibration reduction has been proposed.
