Through the analysis of the tunnel excavation and stability characteristics of the large-scale promenade impedance tailwater surge shaft, the calculation method of the three-dimensional damage of the rock chamber in the large-scale promenade surge chamber and the analysis method of the anchorage support are established. The stress characteristics of the lining structure of the surge controlled surge shaft are analyzed. The calculation method of the cracking of the concrete lining structure and the formula of the structural reinforcement are given.
