Abstract: A spanwise segment connection structure for wind turbine blades includes a first segment and a second segment provided along the length direction of the wind turbine blade. At least one splicing surface is provided between the first and second segments; and a structural adhesive layer provided at the splicing surface for splicing and fixing the first and second segments; wherein the bonding length of the structural adhesive layer conforms to the inclination angle of the slope structure, and a biaxial fabric reinforcement layer is provided on the outer side of a skin interface of the splicing surface. The weight of the blade is reduced and the production cost is reduced through the bonding and fixing of the first and second segments. The splicing surface in form of the slope structure increases the bonding area and reduces the stress concentration on the splicing surface of the first and second segments.
