Micro-earthquake Test Research on Propagation Characteristics of Shock Wave in Road Base

在试验路段,通过试验模拟车辆对路面的行车作用,利用HZ-MS48型微地震监测系统采集微地震波,并对微地震信号进行处理和分析。阐述微震数据采集试验的方案及过程,对几种微地震波形进行分析对比,研究冲击震动波在路面基层中的传播特性。同时,以其中一个典型微地震事件定位为例,验证微地震监测的定位精度,为交通车辆监测提出一种新思路。

This paper simulates the effect of moving vehicles on road via test in sections under test, utilizes HZ -MS48 type microearthquake monitoring system to collect the earthquake waves, and processes and analyses the micro - earthquake signals. In the paper, the scheme and process of micro - earthquake data acquisition test are described, a few micro-characteristics of the shock wave earthquake waveforms are analyzed and compared, and the propagation in road base are also investigated. In the meantime the paper, adopting an example of positioning one of the typical micro- earthquake events, verifies the positioning accuracy of earthquake monitoring as to put forward a new idea for monitoring traffic vehicles.
