Problems solved by technology

[0003] However, the environment of the foundation structure of offshore wind power generation is very complex. In addition to the vertical force of the structural weight of the wind turbine tower transmitted from the superstructure, the load also includes the horizontal force and bending moment transmitted from the wind load to the foundat

Abstract

The invention relates to the field of foundation structures, and discloses a four-cylindrical-foundation combined foundation structure system of a concrete support structure. The system comprises four cylindrical foundations of which center points are connected to form a square; the top of each cylindrical foundation is connected with a concrete ballast tank structure; a vertical concrete connecting piece is connected between each two concrete ballast tank structures; a concrete connecting baseplate is arranged in a space defined by the four vertical concrete connecting pieces; a concrete column positioned in the center is arranged at the upper part of the concrete connecting baseplate; a concrete connecting top plate is arranged at the top of the concrete column; and the concrete column is connected with each concrete ballast tank structure through an inclined sheet variable-section concrete structure. The system effectively and similarly converts higher bending moment transferred from the upper structures to tension and pressure at the cylindrical foundations through the concrete support structure similar to a special-shaped column so as to exert maximum bearing capacity of the cylindrical foundations to save materials.

Description

technical field [0001] The invention relates to the field of basic structures of ports, oceans, water conservancy and bridge engineering, and in particular relates to a basic structure in which multiple tubes are combined to optimize the stress of the tube-shaped foundation. Background technique [0002] At present, in the field of marine engineering such as offshore wind power projects, the foundation structures usually have pile foundations, gravity foundations, jacket foundations, negative pressure foundations and floating platforms, etc. These foundation structures usually require large machines for transportation and installation , resulting in higher construction costs and longer construction periods. Compared with the traditional foundation structure, the cylindrical foundation is widely used in marine engineering due to its low cost, convenient construction, safe and reliable use, and recyclable reuse. [0003] However, the environment of the foundation structure of...
