Research on Safety Monitoring and Numerical Calculation of Concrete Faced Rockfill Dam in Low-Latitude and High-Altitude Area
Concrete faced rockfill dam( CFRD) is one of the most competitive and prospective dam type that with great potential in dam engineering. Most were based on experience together analogy works to be carried out. In both low- latitude and plateau area,the theoretical research and engineering experience are deficient,it is can't content with the design and construction of the CFRD only by this way. It is imminent to set up a numerical calculation model which adapt to this area. Based on prototype monitoring data to calculate and analyze the CFRD of Li Di Ping which have been built in this area,calculate and analyze the existing numerical calculation model,use the Duncan E- B model and AutoBANK procedures to simulate the dam. The results show that analog values and measured values are basically consistent,the Duncan E- B model and AutoBANK procedures can be used to analyze the stress and deformation properties of the dam in this area. It will provide a reference for the design and construction of similar projects.
