Abstract
Taking the circulating water diversion tunnel project of a large power plant as an example, a new type of underground excavation technology, namely vertical jacking construction technology was studied. The reaction force of the bottom of the tunnel was calculated accurately by establishing the calculation model, and the countermeasures to overcome the reaction force were put forward. At the same time, the vertical jacking process, control points and monitoring content were discussed. Through the above research and analysis, it can provide reference and help for the construction of similar projects, and promote the further development of the technology.
