,in construction for spillway section of phase-Ⅱproject at TGP.

In the actual operation of the post-construction water and cooling water supply through water pipes in concrete at the spillway section, operation procedures and calculation methods should be applied flexibly according to the duration of joint grout, the internal temperature of dam, the construction progress of monolithic blocks.

In this paper, stress analysis of the spillway section of the Three Gorges Dam is made with 3-D Finite Element Method (FEM) under the action of gravity, water pressure, sediment pressure and uplift.

A fieldbus based spillway gate electrical control system is introduced in this paper, including its structure, function and configuration.

Ⅰ & ⅡB including mainly the spillway section and blocks Nos.

The Three Gorges spillway section has a special geological condition featuring developed fine and through net fissures with steep dips, resulting in difficulty in cement grouting, water loss and increase in grout concentration, widely piping at locations and excessive grout takes in some hopes.
