基于TSP地震波法的长大隧道不良地质探测
|
摘要
应用TSP203地震波法对某长大隧道不良地质区段进行了超前探测,对TSP系统所采集到的数据进行分析,判定了断层破碎带和隐伏含水构造发育的规模与位置,并在TSP报告指导下进行超前钻探,进一步精确确定不良地质区段位置,为超前预注浆加固提供了参数。对开挖后的地质情况进行了跟进观测,验证了TSP地震波法对不良地质探测的准确性与有效性,对类似工程有一定的指导意义。
The seismic wave TSP(Tunnel Seismic Prediction) method is widely used in the geological condition prediction in recent years.In this paper,the TSP Model 203 was used to detect the adverse geological conditions of a long tunnel.Based on the data collected,the locations and limits of the fractured zone and the groundwater rich area can be reasonably determined.The further explorative drilling guided by the seismic wave predictions can verify these adverse geological conditions.The detection and drilling results provided technical bases for the advanced grouting in the fractured zones.The monitoring results during and after the construction indicate that this method is satisfactory.
