When applying reliability analysis to the monitoring of structural health, it is very important that gross errors–which affect prediction accuracy–are included within information. An approach using errors identification and a dam safety model for deformation data concrete dams proposed in this paper. It can solve problems strong nonlinearity difficulty identifying eliminating dams. This new met...

In this paper, case study on outlet cracking is first conducted for the Goupitan and Xiaowan arch dams. A nonlinear FEM method is then implemented to study effects of the outlets on integral stability of the Xiluodu arch dam under two loading conditions, i.e., normal loading and overloading conditions. On the basis of the case study and the numerical modelling, the outlet cracking mechanism, ri...

Dam deformation monitoring can directly identify the safe operation state of a dam in advance, which plays an important role safety management. Three-dimensional (3D) terrestrial laser scanning technology is widely used field due to its fast, complete, and high-density 3D data acquisition capabilities. However, point clouds are characterized by rough surfaces, discrete distributions, affect acc...

Abstract Recorded ground accelerations at various locations of Karun III Dam during November 20, 2007, were recorded by an array accelerometers located on the dam. In terms amplitude and phase, these show non-uniformities in different elevations. this paper, effect non-uniform motions seismic response dam taking dam-reservoir-foundation interaction into account is investigated. The EACD-3D-2008...
