BP Model Application in the Prediction of Concrete-crack Opening of Underground Powerhouse Crowns
Dian Zhu · Journal of Sichuan University · 2002
This paper focuses on the characterstics of cracks of Ying xiuwan underground powerhouse arch crowns in Sichuan Province and establishes crack opening BP model.The application of practical prediction shows that the precision of model is satisfying.The method avoids the difficulty of expressing the relation between the crack opening value and its influence factors.Meanwhile the influence of uncertainty of every factors is also avoided.According to the trend of crack and the precision of BP model,reinforcement measures must be takern quickly.
