Seepage Safety Analysis of Reservoir Dam Based on Online Monitoring Data
Taking west dam of Shaomen plain reservoir in Jiyang District of Jinan Municipality as an example,through sorting and analyzing the online monitoring data of pressure pipe water level,finite element method was used to invert the equivalent permeability coefficient of the dam composite geo-membrane,and re-check the seepage safety of the dam.The results show that the variation trend of the water level in the pressure measuring pipe is consistent with that in the reservoir,the positive correlation is good,and the reliability of the measured data is high.The seepage flow in the dam body is normal and stable,and there is no obvious change trend.The hydraulic gradient of dam foundation and the gradient of escape point under each working condition are less than the allowable gradient,and the seepage stability of the dam meets the requirements.
