| Abstract: | The Three Gorges double-way and five-step shiplock has a total length of 6 442 m, with a main section of 1 637 m. The excavation was executed in two stages, i. e. , cover excavation of large area and northern slope cut in the first stage and deep trench excavation of the main section in the second stage. The slopes and the chamber walls were supported with anchor cables, anchor bars and shotcrete. The Engineer performed quality control over the site construction by a combined method including dynamic and key locations control, prior control, control in process, and ex post facto inspection. |
