The invention discloses a side span shape finding method adopting resultant force control in a horizontal plane. The method comprises the following steps: taking a vertical component force of a side span main cable at a theoretical vertex as an iterative variable, taking a vertical coordinate of the theoretical vertex or an anchoring point at a splay saddle as an iterative target, adding a new control item, i.e., an included angle between a resultant force in a horizontal plane and a longitudinal axis of a side span end part, and carrying out loop iteration on a side span cable system until aprecision requirement is met. According to the side span shape finding method, it is guaranteed that the longitudinal component force and the transverse component force of the cable force on the towertop are equal, in other words, the resultant force in the horizontal plane is equal, the bridge tower can be completely vertical, the obtained side span line shape and the obtained middle span line shape do not have folded angles on the tower top, and the transverse coordinates of the theoretical vertex or the anchoring point of the splay saddle can be accurately calculated. When the bridge forming state of the space cable suspension bridge is determined, the side span shape finding method controlled by the resultant force in the horizontal plane is successfully applied to the design of a large canyon glass bridge with the main span of 430 m.
