强夯振动对高铁桥墩造成的地震效应检测

Seismic Effect Detection of High Speed Railway Bridge Piers Caused by Dynamic Compaction

为确保高铁设施的安全,针对强夯振动的特点,根据场地的地质条件,选取离桥墩最近的夯点进行检测,在附近三个桥墩处设置三组检测点,每组三个分向(径、切、垂),对强夯造成的地面振动速度进行了检测,结果显示,根据国家标准,该次强夯振动不会对桥墩产生破坏性影响。

In order to ensure the safety of high-speed railway facilities,the nearest dynamic compaction point is selected to detect the pierbased on the characteristics of dynamic compaction vibration.Three sets of test points are set in the vicinity of the three piers, Each group consists of three parts(radial, tangential and vertical),and the ground vibration velocity caused by dynamic compaction is tested. According to the national standard, the dynamic compaction vibration will not have a destructive effect on the bridge piers.
