摘　　要：马桑哨隧道通过地段岩溶发育、水流量大、断层破碎带多,地质条件十分复杂。施工过程中采用了包括TSP203、地质雷达、地面调查、地质素描和超前水平钻孔多种方法相互印证、相互补充的综合地质预报技术。以马桑哨隧道超前地质预报为例,通过开挖后揭示的信息与预报结果对照,表明了综合超前地质预报的准确性。对类似工程的超前地质预报工作具有一定的指导和借鉴意义。The Masangshao tunnel passes through a section with complicated geological condition. The ground is rich in karst and underground water, and has many faults and fractured zones. In the process of construction, a comprehensive geological prediction was adopted. It included the TSP203, geologic radar, regular geologic analysis and advance horizontal boring. They verify and supplement one another. The paper compares the geological predic- tion of Masangshao tunnel with the information revealed after excavation. This comparison shows the accuracy of comprehensive geological prediction. The above-mentioned practice has certain lessons and guiding significance to geological prediction of similar projects.
