Stability Analysis of Gravity Dam Using Finite Element Method and Particle Swarm Optimization
Structural stability analysis is the key aspect of a gravity dam. The safety of a dam relies on its capabilities to handle all external static and dynamic forces acting on it. This study includes stability analysis of a non-overflow section of gravity dam using 3D finite element method (FEM) and particle swarm optimization (PSO) method. The four-node quadrilateral modal element analysis was carried out by using FEM. Further PSO method is applied for stability analysis of gravity dam as it has very few parameters to adjust during analysis. Structural stability analysis is performed on a 33.5 m high non-overflow section of the gravity dam “Ban Sujara Project, Madhya Pradesh, India.” The analysis of the dam was carried out having a height to width ratio of 1.236, which comes under seismic zone II. The results obtained by using 3D FEM and PSO satisfy structural safety evaluation limits as per standards specified in codebooks. In FEM, virtual scale modeling is difficult and time-consuming to find error and fix it as compared to PSO. PSO provided an efficient and accurate solution and presented as a point or be extended to n-dimensional space. The structural stability safety checks results are graphically presented for the accuracy of manual calculations. The result obtained using FEM is 92%, and PSO 96% of limiting values is achieved per the Indian Standard codebook.
