Optimization of Earth Dam Cross-Sections Using the Max-Min Ant System and Artificial Neural Networks with Real Case Studies
This study introduces ODACO, a comprehensive program for optimizing earth dam cross-sections with berms using a dual approach: the Max-Min Ant System (MMAS) for identifying critical slip surfaces and efficient shell geometries, and Artificial Neural Networks (ANNs) for rapidly and reliably predicting seismic responses. This integrated framework aims to replace conventional trial-and-error design methods, leading to more economical, reliable, and practical earth dam configurations by incorporating slope stability, operational constraints, and seismic performance requirements across all loading conditions.

MMAS
Core Earth Dam Optimization Algorithm
The study leverages the Max-Min Ant System (MMAS), an advanced variant of Ant Colony Optimization (ACO), for optimizing earth dam cross-sections. MMAS excels in constraint-dominated geometric optimization problems. Its key features include pheromone updates only on best paths, upper and lower pheromone limits to prevent stagnation, initial high pheromone concentration for exploration, and reinitialization mechanisms to escape local optima. This robust approach identifies the most efficient dam geometries while satisfying stability and geometric constraints.

ANNs
Rapid Seismic Performance Assessment
Artificial Neural Networks (ANNs) are integrated to provide rapid and reliable predictions of seismic responses for optimized dam cross-sections, acting as an efficient alternative to computationally intensive dynamic analyses. The ANN model uses a hybrid training strategy (back-propagation with Levenberg-Marquardt) and an optimized input set (10 parameters instead of 14) for enhanced performance. It achieved high correlation coefficients (0.9-1.0) with dynamic analysis results and maintained approximation errors below 20% across a wide range of PGA levels, demonstrating its robustness for practical applications.
