Method for determining position of wire strand separation point in splay cable sleeve

The invention relates to the technical field of suspension bridge design, in particular to a method for determining the position of a wire strand separation point in a splay cable sleeve, which comprises the following steps: obtaining a splay sleeve local coordinate system Ws by converting an overall coordinate system W0; establishing a wire strand coordinate system Wi for each wire strand, and establishing an anchor surface coordinate system Wm; calculating the initial tangent angle beta i of each strand relative to the central axis of the splay sleeve at the separation point, and calculatingthe tension of each strand; aiming at the ith wire strand, assuming that the tangent angles of the ith wire strand relative to the central axis of the splay sleeve at the separation point are beta1 =betai and beta2 = tbetai respectively, and calculating and obtaining an updated tangent angle; verifying whether the force is balanced or not by using the updated tangent angle, if not, enabling thetangent angle of each stran
