Dam Survey Displacement Monitoring Model and Its Establishment

Based on the analysis of the affecting factors of dam displacement, a general formula of multidimensional, multipoint and multidirectional displacement model for dam safety monitoring was put forward. Through FEM calculation together with statistic analysis, the problem, which is difficult to determine the environmental effecting part on the displacement such as water pressure and temperature, was solved. Further more, a complete simulation model system of displacement was built up. The result of application is satisfactory.
