“The basic principle of the crown beam method is to divide the arch dam into a series of arch systems, considering only one cantilever beam at the arch crown, and determining the load distribution among the arch beams based on the condition that the radial displacements at the intersection points of each layer of arch rings and the crown beam are identical； Furthermore, the radial load distributed to the arch ring is evenly distributed from the crown of the arch to its ends; it is assumed that the stress conditions in the beam systems on both sides of the arch crown are the same as those in the arch crown beam itself. After load distribution, the arch stress of the rear arch is calculated using the pure arch method, while the stress of the beam is calculated as that of a cantilever beam.
