Dam Seepage Monitoring Model Based on Dynamic Effect Weight of Reservoir Water Level

For the lag effect of reservoir water level in dam seepage monitoring, through in-depth theoretical analysis, it is concluded that the nature of problem is that seepage field at a certain time is a instantaneous result of all previous reservoir water levels interaction, and effect weight of every reservoir water level not only relates to state properties of dam, but also relates to itself, such as size, change rate etc. By introducing the concept of reservoir water level effect proportion, dynamic effect weight of reservoir water level is obtained and a dam seepage monitoring model based on dynamic effect weight of reservoir water level is put forward, which additionally considers the effect of reservoir water level on effect weight. Examples show that the dam seepage monitoring model based on dynamic effect weight of reservoir water level more tally with the actual and its accuracy is higher.
