摘　　要：岩溶隧道地形和地质条件复杂多变,盲目施工常会造成突水、突泥和塌方等安全事故,深入细致的超前地质预报工作为隧道信息化设计和施工提供了重要的依据。以鸡场坪隧道为工程背景,介绍了TGP206地质超前预报系统破译技术基本原则,提炼了综合成果图破译原则和破译步骤,最后通过对比YK64＋885~YK64＋735里程初步推断结果和开挖后工作面实际地质情况,证实了综合成果图破译预报的可行性和准确性,对类似工程有一定的借鉴意义。As the complicated geological and variable topographical conditions in karst area,the rough construction of tunnel could results in accidents,such as water flush,mud inrush,collapse and so on.The thoroughgoing and detailed advance geology prediction can provide important basis for digital tunnel design and construction.Taking Jichangping tunnel project as engineering background,the fundamental principles of interpretation technology for TGP206 advance geology prediction system are introduced in this paper,and the interpretation principles and steps of comprehensive geologic and geophysical map are drew up.Finally,by contrasting the elementary prediction results with actual geological conditions of the working face after excavating in YK64＋885～YK64＋735 section,the feasibility and accuracy of geological prediction by interpreting comprehensive result maps are conformed.It is provides a reference to similar projections.
