| Abstract: | Large diameter cast-in-place thin-walled tubular piles were employed to support an excavation in deep soft clay layer, which was driven by a high-frequency hydraulic vibratory hammer. The economic and technical parameters of different types of cast-in-place piles were analyzed. The joint construction method between the supporting piles and basement subfloor was presented. And the reinforcement design method for structures with annular section was elaborated. It is indicated that the cast-in-place tubular piles can be well adopted in coastal soft clay excavations. |
