| Abstract: | Due to continuous settlement, natural deep foundations on soft clay can not reach after the criterion of completion checkup. So, micro steel pipe pile will be applied into it. In this paper, an engineering case on this method is introduced. At first, main causes to continuous settlement are analyzed in detail owing to characteristics of load and soft clay. Then, some important methods on design, construction and checkup of micro steel pipe pile are introduced, and optimizing method on it is put forward. All these approaches are used for reference. |
