The invention relates to a discontinuous cross brace structure for a high-sea-condition high-speed semi-submerged platform, which comprises a cross brace and a high-strength cable, the cross brace is divided into two sections, the middle position of the semi-submerged platform is disconnected, an anti-collision and dislocation matching structure is arranged at the disconnected position, and the two sections of cross brace are connected through the high-strength cable to bear an axial tensile load. A transverse support end toggle plate is arranged at the connecting position of the transverse support and a stand column of the semi-submersible platform to provide transition. By the adoption of the intermittent cross brace structure for the high-sea-condition high-navigational-speed semi-submersible platform, stress concentration on the cross brace can be effectively reduced, under the condition of high-sea-condition large deformation, compared with an existing communicated cross brace structure, the phenomenon of cross brace stress concentration caused by overall large deformation of the platform can be greatly reduced, and the service life of the platform is prolonged. And the possibility is provided for the design of the large-size semi-submersible platform under the high sea condition.
本发明涉及一种用于高海况高航速半潜平台的间断式横撑结构,包括横撑、高强缆,所述横撑分为两段,在半潜平台中间位置断开,断开位置处设有防撞和错位匹配结构,两段横撑中间用高强缆连接,用以承受轴向拉伸载荷,横撑与半潜平台的立柱连接位置设有横撑端部肘板提供过渡。采用本发明的用于高海况高航速半潜平台的间断式横撑结构,可以有效的降低横撑上的应力集中,在高海况大变形的情况下,相比于目前连通式的横撑结构,可以大幅降低由于平台整体大变形引起的横撑应力集中现象,为大尺寸高海况下的半潜平台的设计提供了可能。
