Abstract: In construction of diversion tunnel of hydropower station or other underground chamber, the collapse, the solution cavity, high pressure surging water, large fault and other adverse geologic sections often appear, which cause large potential hazard for construction safety. Usually the geological drilling was adopted to explore the geologic situation ahead, but this method can explore only shorter distance and consume longer time. The use of TSP203 advanced geologic prediction system can solve abovementioned problems effectively. The successful application of this system in construction of hydropower engineering has provided reference for other similar underground complex project construction.

Key words: TSP203 advanced geologic prediction system, adverse geologic section, advanced geologic prediction technology, diversion tunnel of hydropower station, consume
