doi:10.3901/JME.2018.10.167

Abstract

Abstract: Shield cutting tools play a key role in the process of shield machine tunneling, and its reasonable configuration selection affects the success of the project. For the reasonable configuration and the geological applicability of shield cutting tools, an intelligent configuration method based on PSO-BP neural network hybrid algorithm is put forward, where the configuration principle of shield cutting tools is considered. The successful shield construction cases are used as sample data to train the relationship model, which is established between geological conditions and the types of shield cutting tools. And the trained model can achieve intelligent recommendation for the configuration scheme of shield cutting tools. The trained model is tested by engineering case, and the test result is compared with the actual configuration scheme. The test results show that, the PSO-BP neural network algorithm can not only achieve the reasonable recommendation on configuration scheme of shield cutting tools, but also it has significant improvement compared with the BP neural network algorithm in two aspects of calculation accuracy and training time.

Key words: BP neural network, intelligent selection, particle swarm optimization, shield cutting tool
