摘　　要：基于TSP探测原理,分析TSP预报倾斜岩层分界面误差产生原因.结合实际工程实例对比分析,探讨TSP对倾斜岩层预报结果产生的误差与倾斜岩层与隧道轴线之间夹角的规律,总结得出不管隧道轴线与倾斜岩层之间的夹角的大小如何,预报的倾斜岩层分界面的位置都会比真正的分界面位置延后出现.Based on the detection principle of TSP,the reason to produce errors of the interface of the inclined stratum predicted by TSP was analyzed.Combined with comparative analysis of engineering examples,the regularity of angle and error of inclined stratum predicted was discussed.The result showed that the interface of the predicted inclined stratum would always appear later than the real interface,which had no relation with the angle between the inclined stratum and the axis of tunnels.
