摘　　要：随着科学技术的飞速发展,各类精密科学仪器对于环境振动的要求也愈发严格,而高速铁路列车作为现代生活中一种常见的交通工具,其对周边场地的环境振动具有较大影响。以位于城际高铁附近的某精密仪器建筑拟建场地为例,研究高铁对建筑场地环境振动的影响。通过在距离高铁不同位置处布置测点,得到现场实测数据并对高铁在不同距离处引起的环境振动进行分析,通过分析结果对该场地中高铁引起的环境振动随距离的衰减特性进行分析,根据精密仪器建筑场地对环境振动的要求对该拟建场地进行了评价,并提出了建筑场地对于高铁的退让距离。With the rapid development of science and technology,kinds of precise scientific instruments have increasingly strict requirements on environmental vibration.As a common means of transportation in modern life,high-speed railway has a great impact on the environmental vibration of the surrounding sites.The effect of high-speed railway on the environmental vibration of the construction site was studied by taking a precision-instrument construction site near the intercity high-speed railway as an example.Through different monitoring location laying out high-speed railway through the distance,the field data was measured and the environmental vibration caused high-speed railway by different distance was analyzed.Based on the analysis results,the attenuation with distance characteristics of environment vibration caused by high-speed railway was analyzed.The proposed site was evaluated according to the environmental vibration requirements of the precision instrument construction site,and the concession distance of the construction site to the high-speed railway was proposed.
