Demand analysis and forecast on the freight transportation of Three Gorges Project

The main functions of the automatic hydrologie tele-metering system for the Three Gorges project are to collect the real time data of water level and precipitation of the region from Chongqing to Yichang, and the weather data of the dam sites of Three Gorges and Gezhouba.

When the biggest shiplock, spillway and powerhouse in the world were incorporated in the Three Gorges project a series of key technical challenges faced the designer of the metal structures.

Research summary of key technologies on electro-mechanical design of TGP

The most of shaft wells of TGP s permanent shiplock characterize as large section, shaft well group, double steel bar, and large amount of accurately embedded metal structure and especially for the lower shiplock chamber section, the structure is complicated and the steel bar is dense.

The scour and change of the riverbed between the Gezhouba Project and the Three Gorges Project since the beginning of the Three Gorges Project are studied according to the measured data and the effect of building the Three Gorges Project on the riverbed change between the two dams is evaluated.
