摘　　要：随着高速铁路、公路的快速发展,TSP203plus系统广泛用于隧道施工中超前地质预报。该系统能够较准确地提供掌子面前方断层破碎及其影响带、节理裂隙发育带和软弱带等不良地质体位置;但对岩溶、含水或富水构造的探测还有待探索,至今仍是工作的重点和难点[1]。该文结合近几年的应用实例,简述了TSP203plus的工作原理,然后重点分析该系统在岩溶隧道中的应用,力求探索该系统在岩溶隧道超前预报中的规律,其研究成果具有一定的参考价值。With the rapid development of high-speed railway and freeway,TSP203plus system is applied widely in advanced geological prediction of tunnel construction.It can determine accurately the location of the bad geology body in the front of the tunnel face,including the fractured zone in fault and affected zone,the joint fissure zone with well development,and the weak rock zone,etc.However, it is the emphasis and difficulty for detecting the karst,rich water structure which geophysicists make their efforts up to now.Referring to the examples in recent years,it firstly summarizes the work principle of TSP203plus,then mainly analyses the case application in karst tunnel,and explores the regular of advanced geological prediction in karst tunnel,and its study results have some reference value.
