| Abstract: | The Monitoring results by muhi point extensometer and anchor cable dynamometer show that the entrance slope at Zipingpu Dam has deformed outwardly after the Wenchuan earthquake. The surface displacement increment is 3. 684 to 11. 518 mm and the anchor load increment is -16.9 to 86.1 kN, showing that the slope is basically stable. And the study reveal that the deformation has been most affected by the main shock rather, in stead of the aftershocks. |
