Abstract

An integrated static and dynamic risk evaluation system was developed to classify the potential risks of large river-crossing buildings over the South-to-North Water Diversion Project. The system constructs an index based on design and construction quality information, the characteristics of different types of buildings and external conditions including the hydrology and geology. The static risk is given by a neural network model while the dynamic risk is related to flood, freezing, flushing and tensile stress conditions. The integrated risk index compares well with results in the literature with good results given in a case study.

Key words

river-crossing construction / risk identification / neural network / dynamic risk / risk index
