Cable length adjustment amount solving method for adjusting displacement of cable-stayed bridge
The invention discloses a cable length adjustment amount solving method for adjusting displacement of a cable-stayed bridge. The cable length adjustment amount solving method comprises the following steps that a cable length-anchor point displacement influence matrix is solved; determining a target vector of displacement adjustment; determining an anchor point displacement participation coefficient; and iteratively solving the cable length adjustment value. The method for stably, conveniently and rapidly solving a group of uniform and reasonable cable length adjustment amount is provided, the cable length correction amount obtained through solving is uniform and reasonable, the calculation result is superior to that of an existing conventional least square method, the iteration method is obviously superior to an existing calculation method in calculation, the design time is greatly shortened, and the design efficiency is improved. And the working efficiency is improved. The method can be used for quickly and accurately adjusting the configuration of the cable-stayed bridge, including tower deflection and girder line shape.
