Research on slope stability of Yanshan iron mine after water control works in east slope

摘要

Based on the problem of underground continuous diaphragm wall in the east of Yanshan open-pit slope of iron mine, Si Jiaying, three typical sections of the slope are selected and calculated with numerical simulation method, slope stresses under water inflow condition and apply underground continuous diaphragm wall method are analyzed.Results showed that the slope stability is not up to standard under water inflow condition and there exists local instability phenomenon.After applying underground continuous diaphragm wall to control water, slope stability is improved significantly and up to the requirements.
