摘要

爆破激发的地震波在围岩中传播时,部分地震波会被反射。隧道前方地震预报法用TSP203 Plus接收器将反射的地震波进行收集并转化为数据,利用TSPwin软件对数据进行处理,获得前方地层的地质力学参数,评估隧道掌子面前方围岩与地层情况。该方法具有预报距离远、精度高,对施工干扰小等优点。
While seismic waves stimulated by blasting spread in surrounding rock,part of the earthquake wave will be reflected.Ahead-of-the-tunnel earthquake prediction uses TSP203 Plus receiver to collect reflected the waves and transform them into data.TSPwin software is used to process the data,geomechanical parameters of the geological strata ahead are obtained and the surrounding rock and geological strata ahead of the tunnel face are evaluated.The method has features of long-distance forecast,high accuracy,little interference and so on.
