Abstract


In recent years , high pier and long span continuous rigid frame bridge with its driving smooth and comfortable , ease of construction , is conducive to the maintenance and other advantages are increasingly built to promote the theory of bridge design , construction techniques and the development of the construction control method . However, the bridge construction control method in a way is a lag in bridge design theory and construction technology , control theory immature monitor backward technology and other factors limit the development of bridge construction control technology and breakthroughs . Artificial neural network method was applied to the bridge construction control technology as the bridge workers , bridge construction control provides a useful reference and ideas . This method is still in the theoretical discussion and projects for the trial stage , there are still many problems to be solved . Thesis entry point , trying to solve the artificial neural network is applied to some of the problems encountered in the bridge construction control , thereby enriching and improving the existing bridge construction control technology . Bridge workers in this application of artificial neural network to bridge construction control to select the input , output vector with considerable arbitrariness and experience component . Bridge construction control characteristics , the paper analyzes the many factors that cause elevation error of linear control , the introduction of a \the number of neurons in the input layer structure , reasonable and completeness , either consider various error factors in a more comprehensive manner and achieve the independent input of each vector , the purpose of reducing the number of dimensions and the network size . The paper will also examine the application of the results to the linear control of Xu ditch Bridge , better stage , and - span continuous rigid frame bridge construction control the temperature of the complex impact of ultra-high pier the long cantilever temperature correction method .
