大坝实测位移模型及建模方法

Dam Survey Displacement Monitoring Model and Its Establishment

根据影响大坝位移的因素分析,给出大坝安全监测多维多测点多方向位移分析模型的一般形式,提出利用有限元计算与统计分析相结合的方法,解决了实测位移水压、温度等分量不易确定的问题,得到了一个较完整的大坝实测位移建模体系。

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.
