Abstract:The observation results of Gaoya leveling is abnormal from January 2017 to April 2018. In order to study the mechanism of this anomaly, based on the quantitative simulation by 2-D irregular load model and the qualitative and quantitative analysis of impact factors such as reservoir capacity, precipitation and underground water level, the following understanding is obtained: 1) The change of Gaoya reservoir capacity load has a weak influence on the Gaoya leveling, which is not the main interference factor of the Gaoya leveling. 2) The deeper reason for the abnormal change of Gaoya leveling is that the change of underground water level affects the inconsistent deformation of rock mass at both ends of the level through water-rock action. The subsequent changes of observation verify the rationality of the new understanding about the mechanism of the abnormal changes.
