| Abstract: | In the paper,some thoughts are introduced on secondary welling method in rapid construction.They are based on holistic analysis of constraints of tunneling and shaft lining reverse construction technique in ventilation shaft construction work where well method is employed,such as long duration,high risk,high cost and poor efficiency.These ideas have been verified through practice.And they might provide reference for similar engineering construction projects in the future. |
