摘要
研究目的:拟建某铁路以高架桥线路形式穿越上海外高桥保税区,距某公司拟建芯片加工厂约250 m。为确保芯片加工厂正常生产的振动环境,特对高架铁路振动进行类比测试分析并根据测试结果提出防振动措施。研究结论:芯片加工厂所在地块已受周边城市道路集装箱卡车振动影响,振动值已超过芯片加工车间基础容许振动速度;对既有沪杭线类比监测表明,旅客列车、货车会车时,距线路250 m处地表振动值与芯片加工厂环境振动现状值相当,超过容许振动速度值。考虑到该公司在距铁路线500 m有建厂的经历,研究主要论证通过采取减振措施使距铁路外轨中心线250 m距离的振动水平相当于500 m距离的振动水平,研究表明减振措施可行。
Research purposes： The planned Shanghai - Nantong Railway will pass through the Shanghai Waigaoqiao Free Trade Zone on viaduct and it will be about 250 m away from a chip processing plant. In order to ensure the normal production of the chip processing factory, it is necessary to test and analyze the vibration induced by the elevated railway and present the anti -vibration measures according to the test results. Research conclusions：The vibration value of the place around the chip processing factory has exceeded the allowable vibration velocity for the foundation of the chip processing workshop because of the vibration induced by the container truck on the peripheral road. The similar vibration tests and monitoring for the existing Shanghai - Hangzhou Railway showed the vibration value of the ground 250 m away from the track was equivalent to the that of the chip processing factory when the passenger train met with the freight train and it exceeded the allowable vibration velocity. On consideration of that the building was built in the place about 500 m away from the railway, the study mainly demonstrated how to reduce the vibration level of the place 250 m far away from the railway to being equivalent to that of the place 500 m far away from railway. The study showed the anti -vibration measures were feasible.
