| Abstract: | The foundation pit for the launching shaft of the Qianjiang tunnel shield is 28.25 m in depth, and 48.9 m× 25.4 m in plane. Its supporting structures are composed of diaphragm walls, reinforced concrete girders and steel structures. The diaphragm walls and the inner walls are of the sandwich structure. Different analysis techniques in design are applied to the analysis of the loading conditions of the enclosure walls, the support elements, the walings and the main structure, which and whose expected design aims are presented in detail in the paper. The experience gained in the structural design of the shield launching shaft may facilitate the design work of other similar shafts. |
