| 摘 要： | 为了考虑库水位对测压管水位的滞后效应，引入了库水位滞后影响函数和等效水位，结合三维渗流有限元计算，建立了考虑滞后效应测压管水位混合模型。计算实例表明，该模型能较好地反映库水位对测压管水压的滞后效应，且精度较高。

| Abstract: | The hysteresis function and equivalent level are introduced for discussion on the hysteresis effect of reservoir level on piezomtric level. In consideration of the seepage calculation result of 3-D FEM, a hybrid model of piezometric level is developed, in which the hysteresis effect of piezomtric level is taken into account. Examples show that the result calculated with the model is in good agreement with the observed data. |
