本文总结了地质编录、TSP203、地质雷达、红外探水、超前地质钻探等不同的超前地质预报方法优选原则和关键技术,深入分析了预报技术的重点及难点,通过采用综合超前地质预报技术,比较准确地探明了掌子面前方80～150m范围的地质条件,为制定相应的施工方案、加快施工进度和确保施工安全提供依据。 This paper summarizes the principles and key technologies of different advanced geological prediction methods, such as geological catalog, TSP203, geological radar, infrared water exploration and advanced geologic drilling. The key and difficult points of the forecasting technology are analyzed in depth. By using the integrated advanced geological forecasting technology, The geological conditions in the range of 80 ~ 150m in front of the face are accurately ascertained, providing the basis for formulating the corresponding construction scheme, speeding up the construction progress and ensuring the construction safety.
