The design of Three Gorges Hydropower Station
Zhou Shuda,Xie Hongbing
Strategic Study of CAE 2011, Volume 13, Issue 7, Pages 78-84
Using physical model and numerical simulation techniques, some technical problems were studied systematically, including layout of power station, measures of sediment and floating debris discharging, types of intake, embedded types of spiral case, layout of underground powerhouse tunnel group and block reinforcement. It was optimal in technique and economy with the arrangement of powerhouse at the dam-toe of both banks + underground powerhouse in the right bank, as well as the intake with a single and small orifice. The sediment and debris problems could be solved with disperse sediment ejection and floating debris discharging holes. With the adoption of techniques for spiral case such as heat and pressure preservation, cushion layer and combined embedding, the stable operation of generating units can be guaranteed. The arrangement of tailrace tunnel with sloping ceiling was better than that of tailrace surge tank. The technical requirements related to the embedding type of spiral case were proposed. The reinforcement of huge unfavorable blocks was discussed and the new idea for block reinforcement using anti-sliding piles and normal compressive stress of structural plane was put forward.

The ultra-small spacing tunnel of Jiaozhou Bay seabed tunnel in Qingdao is took for example; the surrounding rock pressure features and support force are analyzed through the field measurement. Results show that the surrounding rock pressure and support force of the after-excavation tunnel are larger than others of the tunnel. This result is different from the theoretical predictions and experimental results of most of the small spacing symmetry tunnel. To alleviate these problems effectively, support parameters are adjusted opportunely; the radial support capacity of the after-excavation tunnel is enhanced, and reinforcement measures of rock pillar are made at the same time. The monitoring results show that the stability of the after-construction tunnel has been effectively controlled, which provides useful reference for the design and construction of similar tunnels with small spacing.
