| Abstract: | To solve the problems in driving of long cold-formed steel sheet piles such as difficulties in pile driving and easy distortion and deformation of piles, this paper derives, on the basis of theoretical analysis, a formula to calculate the maximum vertical length of a slender piles under its own weight and a formula to calculate the exciting force that a pile can withstand, which provides theoretical basis for selection of construction process for extra-long steel sheet piles and which has been veri- fied in the construction of a cofferdam for a ship-repairing dock. The problems in driving of long cold-formed steel sheet piles was then solved the problems and the working efficiency was improved. |
