Abstract

The invention provides a bridge span arrangement method and device, equipment and a readable storage medium, relates to the technical field of bridge construction, and comprises a new thought of performing span arrangement by using artificial intelligence. Aiming at the requirement of intelligent span arrangement, on the basis of a basic principle and a calculation principle of bridge span arrangement and in combination with excellent learning decision-making capability of reinforcement learning, a strategy value network is optimized and output through a Sarsa(lambda) algorithm, and the strategy value network is added into an AlphaGo algorithm; the simulation stage can obtain accumulated rewards corresponding to global simulation with the node as a root node through a rapid cross arrangement strategy, and can also directly find the corresponding maximum accumulated reward in the strategy value network; and finally the maximum one of the two is taken as the actual accumulated reward after the node simulation is finished, therefore, the final operation result of the AlphaGo algorithm is improved.

Description

technical field [0001] The present invention relates to the technical field of bridge construction, in particular to a bridge spanning method, device, equipment and readable storage medium. Background technique [0002] Bridges play a major role in transportation. Building bridges can effectively solve the problem of subgrade settlement, save land resources, and ensure smooth driving. Among them, the layout of bridge spans is a key issue in the scheme design. Bridge span layout requires very experienced designers, and it takes a lot of time, and the results obtained are not necessarily optimal. Now there is an urgent need for a bridge span layout algorithm to replace manual design. Contents of the invention [0003] The object of the present invention is to provide a bridge spanning method, device, equipment and readable storage medium to improve the above problems. In order to achieve the above object, the technical scheme that the present invention takes is as follows:...
