Quota Making of Super-Long Highway Tunnel Based on BP Neural Network

摘要

In construction of super-long highway tunnel, because adopted some new construction method, such as center bore method, quota of it was very difficult. By BP neural network, a new quota-making method of super-long highway tunnel was put forward. Through a great many of training of data samples, quota is more related with actual consumption and it can be dynamically adjusted. The method was successfully used in quota-making of Zhonglanshan tunnel in Qinling Mountains. Compared with coal quota method, it was more accurate.
