摘要
TRT6000隧道超前地质预报技术是采用空间观测方式和偏移成像方法,与TSP、TGP负视速度法、水平剖面法等比较,技术比较先进,能够较好的分析判定掌子面前方隧道围岩速度结构特性,实现了隧道围岩地质结构的精确成像,是目前比较适合地下复杂地质条件下的超前地质预报技术。要想在实际超前地质预报工作中取得好的预报效果,应采用多种方法,地质分析与工程物探相结合等,对不良地质构造、富水带等有效的实现超前预报。
TRT6000 Tunnel Seismic Prediction（TSP） system adopted space observation and migration imaging,the technology of which is more advanced compared with TSP,negative watching velocity and horizontal profile method,velocity characteristic of the surrounding rock in front of the heading face can be decided by this method,accurately image of surrounding rock has been realized,it is suitable for Tunnel Seismic Prediction with complicated geological conditions.Many methods should been used in order to obtained good effects of the TSP,such as the combination of geological analysis and engineering geophysics,which could make a effective prediction for harm geological structure and water enriched zone.
