Seismic quay structure

摘要

PROBLEM TO BE SOLVED: To provide an earthquake-proof quay wall structure capable of economically improving earthquake-proof performance, by setting a steel sheet pile wall of crossing with an existing quay wall as the predetermined extension length, by aiming at earthquake-proof reinforcement of the existing quay wall.SOLUTION: An earthquake-proof quay wall structure 1 of applying the present invention, comprises a steel sheet pile wall 2 provided for reinforcing a quay wall for earthquake resistance and extending in the crossing direction Y of crossing with an existing quay wall 7 and a connection member 6 connected to the existing quay wall 7 and extending in the crossing direction Y. The steel sheet pile wall 2 is provided by integrating a head part 20a of the whole or a part of a plurality of steel sheet piles 20, and the extension length L of extending in the crossing direction Y becomes a half or more of the member length H in the material axis direction Y of the respective steel sheet piles 20.SELECTED DRAWING: Figure 5
