| Abstract: | With an engineering case of ultra-deep foundation pit in Wuhan, based on the common-used deep foundation pit design scheme, the discussion was made on the overall design scheme selection, the selection and design of foundation pit maintenance system, selection of supporting system, foundation pit dewatering method, earth excavation scheme and support-changing plan. The final design scheme is underground continuous wall enclosure 3 internal supports confined water dealt with tube well dewatering. |
