SPAR platform with annular column multi-layer hollow combined structure

The utility model discloses an SPAR platform with an annular column multilayer hollow combined structure, which is characterized in that the platform comprises a platform body (1) and a support column (2) connected to the bottom end face of the platform body (1), the length of the support column (2) is H. A first annular circular truncated cone (3), a second annular circular truncated cone (4) and a third annular circular truncated cone (5) which are sequentially connected are arranged on the support column (2), and the first annular circular truncated cone (3), the second annular circular truncated cone (4) and the third annular circular truncated cone (5) are arranged on the platform body (1). The distance between the top end of the first circular truncated cone (3) and the platform body (1) is about 0.1 H. The height of the first circular truncated cone (3), the height of the second circular truncated cone (4) and the height of the third circular truncated cone (5) are all H. Meanwhile, the radius of the t
