- Abstract:
- In order to verify the rationality of a design scheme for Donghaochong test section of deep tunnel drainage system in Guangzhou City, the first integral physical model of deep tunnel in China was established to simulate and analyze the key hydraulic problems such as exhaustion, surge and energy dissipation during operation of the deep tunnel. Most of the energy could be dissipated by the folded plate shaft, in which exhaustion of the main tunnel could be achieved. The surge and gas explosion intensity generated during the operation of the project was weak. Space of the sump of the pump station could meet the requirement of the pump operation. It was feasible to use flood discharge and water replenishment for hydraulic scouring and silting.
