中文摘要：
研究目的：铁路隧洞施工中，由于地质情况不明，经常出现塌方、涌水、冒顶等地质灾害，十分需要开展地质超前预报方法研究。TSP203系统作为地质预报的主要方法，对其基本原理和工程应用进行研究十分必要。研究结论：建议当前隧道超前预报工作中应以TSP203超前预报系统为主，配合其它物探方法以及地质详细素描、超前水平钻探等非物探方法进行相互补充，相互印证。
英文摘要：
Research purposes： The geological disasters of collapse, water bursting and roof falling often occur in construction of railway tunnel because of unclear geological condition, so very necessary to do the researches on the methods of geological forecast in advance and on the basic principle and engineering application of TSP203 System that is one of main means for geological forecast. Research conclusions：It is proposed that in the geological forecast in advance for tunnel, TSP203 System should be taken as principal means along with other geophysical prospecting methods, geological sketch in details and level drilling in advance for supplementing and verifying each other.
