Abstract: Geotechnical engineering and earthworks have their own complexity and characteristics. Earthwork is an integral part of earth work engineering which has a significant influence on deep excavation supporting system. For the purpose of evaluating the influence of earthwork sequence on the excavation projects, a case history is presented in this paper. Three aspects, which are earthwork sequence on the supporting structure construction, production pile installation, and stability of the supporting structure, are evaluated. The results indicate that the earthwork sequence has a significant impact of the stability of the excavated area and should be carefully designed. The monitoring results demonstrated that actual excavation sequence was appropriate. Suggestions on the excavation projects are also provided in the paper.
