关于火车引起的地表振动及其对附近住宅居室的影响,我国尚未开展这方面的调查与研究。为了了解通过市区的火车振动影响,我们在北京市朝阳区幸福楼地区铁路沿线及附近两座居民楼进行了振动测量和分析,取得了火车引起地表振动的强度和频率分布、地表振动的传导特性、振动对沿线居民住宅楼的影响等重要数据。二测量方法本次测量使用日本制NODE 3160型公害振动计(具有ISO—2631推荐的垂向和水平方向振动频率计权网络),并通过丹麦B&K公司生产的7003记录仪进行了记录。
On the train caused by the vibration of the surface and its impact on residential houses nearby, our country has not yet conducted investigations and studies in this regard. In order to understand the impact of train vibration in the urban area, we measured and analyzed the vibration of two residential buildings along the railway near the Fortune Building, Chaoyang District, Beijing and obtained the intensity and frequency distribution of surface vibration caused by trains. The conduction of surface vibration Characteristics, vibration on residential buildings along the line and other important data. II. MEASUREMENT METHOD This measurement was made using a Japanese NODE Model 3160 Pest Vibrometer (with vertical and horizontal vibration frequency weighting network recommended by ISO-2631) and recorded by a 7003 recorder manufactured by Danish company B & K.
