Ant Colony Optimization Analysis on Overall Stability of High Arch Dam Basis of Field Monitoring
A dam ant colony optimization (D-ACO) analysis of the overall stability of high arch dams on complicated foundations is presented in this paper. A modified ant colony optimization (ACO) model is proposed for obtaining dam concrete and rock mechanical parameters. A typical dam parameter feedback problem is proposed for nonlinear back-analysis numerical model based on field monitoring deformation...
متن کاملApplication of Discrete Crack in Nonlinear Dynamic Analysis of Shahid Rajaee Arch Dam
the nonlinear discrete crack modeling of Shahid Rajaee thin arch dam is considered. The interface elements are positioned such that certain potential separated blocks can form possible failure mechanisms. The dynamic stability of theses blocks are investigated by a special finite element program "MAP-73" which its nonlinear algorithm and interface elements formulation are presented.
متن کاملVertical Contraction Joint Models for Nonlinear Dynamic Analysis of Concrete Arch Dam
Arch dams are generally built in cantilvever monoliths. Vertical contraction joints between monoliths control the stresses due to concrete shrinkage and temperature variations. Past studies in earthquake safety evaluation of the system often show the tensile fracture and local nonlinear deformation of joints. In this paper, some nonlinear joint element constitutive models are presented to exami...
متن کاملVariable-intercept panel model for deformation zoning of a super-high arch dam
This study determines dam deformation similarity indexes based on an analysis of deformation zoning features and panel data clustering theory, with comprehensive consideration to the actual deformation law of super-high arch dams and the spatial-temporal features of dam deformation. Measurement methods of these indexes are studied. Based on the established deformation similarity criteria, the p...
متن کاملA STUDY ON NONLINEAR BEHAVIOR AND SEISMIC DAMAGE ASSESSMENT OF CONCRETE ARCH DAM-RESERVOIR-FOUNDATION SYSTEM USING ENDURANCE TIME ANALYSIS
In the present paper, nonlinear behavior of mass concrete simulated by smeared crack model is combined with Endurance Time Analysis (ETA) method for studying seismic response of arch dams. ETA is a time-history based dynamic pushover procedure in which special predesigned intensifying acceleration functions are used for analysis and estimation of structural responses in various performance leve...
