从理论上推导出振动压路机地面振动衰减关系的简化形式 ,列出振动压路机在洛阳—三门峡—灵宝高速公路施工中产生的地面振动的实验数据。根据实验数据 ,统计得出两种常用型号振动压路机在豫西黄土地区施工振动的地面振动衰减关系。计算得出豫西黄土地区的地基土能量吸收系数。研究表明 ,振动压路机的激振力、振动频率和场地土质条件都是影响振动衰减的重要因素。这就为正确评价压路机在相同土质条件和工作状况下地面振动对附近建筑物的影响提供了科学依据。
The simplified form of the ground vibration attenuation of the vibratory roller is deduced theoretically and the experimental data of the ground vibrations produced by the vibratory roller during the construction of Luoyang-Sanmenxia-Lingbao Expressway are listed. According to the experimental data, the relationship between the ground vibration attenuation of construction vibration of two kinds of commonly used vibratory rollers in the loess area of western Henan is obtained. Calculate the energy absorption coefficient of foundation soil in the loess area of western Henan. The research shows that the vibration force, vibration frequency and site soil conditions are the important factors affecting the vibration attenuation. This provides a scientific basis for correctly evaluating the influence of ground vibration on the nearby buildings under the same soil conditions and working conditions.
