摘要
重型施工车辆重载工况行驶过程中会使道路两侧的房屋建筑产生振动波效应,一旦该振动波强度较大,不可避免导致邻近建筑物或结构物受波及而产生破坏现象。某铁路线路枢纽引入工程在施工过程中,工程重型施工车辆行驶时邻近房屋建筑墙体有一定开裂,为探究评价重型施工车辆行进对沿线邻近建筑物稳定性产生的影响,现场采用TC-4850测振仪监测重型施工车辆行进作业时邻近建筑物地面的振动特性。监测数据表明,该工程重型施工车辆行驶时,对线路邻近建筑物的影响属于允许范围之内。
During the driving of heavy construction vehicles under heavy load conditions,the buildings on both sides of the road will have a vibration wave effect.Once the vibration wave is strong,it will inevitably lead to damage to neighboring buildings or structures.During the construction of a railway line's new introduction project,there was a certain degree of cracking in the walls of adjacent buildings when heavy construction vehicles were driving.The vibrometer monitors the vibration characteristics of the ground adjacent to the building when the heavy construction vehicle is operating.Monitoring data shows that when the heavy construction vehicles of the project are driving,the impact on the adjacent buildings of the line is within the allowable range.
