| Synopsis : In executing a steel sheet piling wall on a soft cohesive soil, it is a common practice to use sheet pilings whose lengths are longer than those of normal length that balances with a given section rigidity. In such case, a sheet pile is tended to be driven with a gap from its guide member, and in order to keep off drawing-down and/or correct an off-alignment driving, the sheet pile is force-deformed so as to permit welding to the guide member. Effect of such force-deformation on driving of sheet pile has been investigated through field tests. As a result, it has been found that the force-deformation increases frictional force of the joint, reduces self-settlement of the sheet pile, and necessitates a more driving work, thus giving adverse effect to execution efficiency. Also, it has been made clear that in case where sheet pile has been driven excessively apart from its guide member, it is better to drive several sheet piles with sheet-by-sheet adjustment in order to correct the off-alignment. |
