[0075] Based on the second constant parameter β, the numerical range of the safety integral of the cumulative horizontal displacement of the dam crest, that is, the safety integral range of the total seepage of the dam body S 2安 , the formula is S 2安 =βL max ~βL min ;

[0076] Based on the third constant parameter γ, the numerical range of the safety integral of the total seepage of the dam body is calculated, that is, the safety integral range of the total seepage of the dam body S 3安 , the formula is S 3安 =γQ max ~γQ min ;

[0095] Furthermore, the method further comprises:

[0096] When the hydropower station dam is in a safe state, the safety level of the hydropower station dam is determined based on the total value of the safety integral of the current preset time.

[0097] Specifically, compare S 总实 and S 总安 to determine whether the value (αP+βL+γQ) is within the value range (αP max +βL max +γQ max )~(αP min +βL min +βL min ), if in, and S 1实 , S 2实 , S 3实 If they are all within the safe range, then according to S 总实 The numerical value of determines the overall safety status of the hydropower station dam in the current time period. The smaller the value, the safer the corresponding safety level. If it is not, it is necessary to detect the cause of the abnormality.
