Technical Field

The invention relates to a pile foundation engineering attachment, in particular to a novel offshore pile wind wave resisting device which plays a stabilizing role in resisting horizontal load of a high-pile marine building, belonging to the field of geotechnical pile foundation engineering.

Background

The pile foundation of the offshore structure is influenced by offshore wind load, current load and the like during the construction or use process. Compared with a low pile foundation, the high pile foundation has smaller horizontal bearing capacity and horizontal rigidity, and is easy to generate larger horizontal deflection under the action of horizontal load.

At present, the common method for solving the horizontal deflection of the high pile foundation is to increase the sectional area of a pile body, improve the horizontal rigidity of the pile body or increase the depth of the pile body inserted into a lower soil layer, thereby improving the horizontal load resistance of a pile foundation. The implementation of the above two methods will improve the horizontal load resistance of the high pile foundation, but also increase the cost of pile foundation construction.
