Global quality assessment of rock works for permanent ship lock of the Three Gorges Project on Yangtze River, China
The ship lock is the main navigation structure for ships to pass through the Three Gorges Dam (TGP), TJ, after the dam is completed. It is designed to maintain and enhance the waterway transportation capacity of the Yangtze River following completion of the 175-m high concrete gravity dam at the TGP site. The ship lock consists of two continuous channels for two-way passage of fleets of up to 10,000 ton capacity. A global assessment of the quality of the engineering works associated with rock excavation for the construction of the permanent ship lock of the Three Gorges Project (TGP) is presented. The ship lock was constructed between 1995 and 1999 by open and deep excavation in a mountain comprising weathered and fresh granite. The meta-synthesis theory (MST) is adopted to quantitatively assess the global quality of such engineering works in rocks. A detailed discussion along with summative data on the rock conditions, the engineering measures and the monitored performance for this quality assessment is presented. The assessment results show that the global quality of the rock engineering works in rocks can be rated as very good and that the rock excavation and stabilisation measures basically meet the high design standards and requirements of the permanent ship lock.
