摘要:
以北京城区内某地铁高架桥为研究对象,采用现场监测、问卷调研等方法,探讨了高架轨道列车运营产生的振动对周边环境的影响规律,结合人体全身振动的接触限值规定,对高架轨道交通振动的影响进行了评价与分析。研究结果表明:以高架桥轨道位置为基点,随着与基点距离的增大,轨道振动的影响逐渐减弱;对于水平方向的振动响应,以平行于列车运营方向的振动分量为主要影响因素。结合不同桥墩的监测结果发现,其振动加速度峰值发生时刻点具有一定的滞后性,在对高架轨道交通振动的环境影响进行评价时,相位差因素应予以必要的考虑。发现体感振动与实测值
Abstract:
Taking some one subway viaduct in Beijing city as the object of study, the vibration influence of the operation of the elevated track trains on the surrounding environment was discussed by field measurement, questionnaire research methods. Combined with human body feeling limit of the vibration exposure, the vibration influence of the elevated rail transit was evaluated and analyzed. The results showed that the influence of the orbital vibration was gradually weakened when the distance from the base point increased by means of taking the position of the viaduct as the base point, and the vibration component parallel to the train operation direction was the main influencing factor of the horizontal direction vibration response. Combined with different bridge pier field measurement results, the time of occurrence of the vibration acceleration peak has a certain lag. Phase difference factors should be considered necessarily in the evaluation of the environmental impact of elevated rail vibration. For the case that there is a big difference between the sensation and the measurement, the results of on-site monitoring should be taken as the main basis for vibration impact assessment. Based on the whole body vibration evaluation standard, the planning rationality of the buildings near viaduct was verified, which provided a favorable reference for regional planning around the viaduct.
