介绍铁路工程爆破振动的检测原理及检测仪器的选择方法。详述爆破振动现场检测流程,依次为:制定检测方案,方案内容主要包括项目简介、测点布置方案、检测频次;安装拾振传感器,包括安装前的工作及安装时的注意事项;安装振动测试仪;设置采集参数;爆破;记录振动波。通过对检测数据进行处理及分析,得到爆破振动的主振频率和最大振速,获得爆破振动传播衰减规律,为铁路工程爆破振动现场检测提供理论依据。

The article introduces the testing principle for blasting vibration in railway engineering and the way to se-lect the test instrument. It specifies the steps to conduct a field test on blasting vibration,successively：to develop atest scheme,with the contents mainly including an introduction to the Project,the measuring point layout plan andthe test frequency;install the vibration pick-up sensor,including pre-installation work and matters needing atten-tion for installation;install the vibration tester;set and acquisition parameter;blast;record the vibration wave.By processing and analyzing the test data,it can obtain the master frequency and the maximum vibration velocity ofblasting vibration,as well as its propagation attenuation rule,thus providing the theoretical basis for field test onblasting vibration in railway engineering.
