Calculation of allowable Volume for Gallery in a Gravity Dam Body

The effect of openings is generally neglected in the design of dam but it is considered when openings are large. Large openings create critical zones for tensile stresses in the dam. Stress concentration inside the dam increases with the openings in the dam which can result in the failure of the dam. Hence, it is necessary to analyses large opening inside the dam. By increasing the area percentage of opening and varying the location of opening the analysis is carried out. For this purpose, the percentage of the area of opening varying from 0.5% to 10% under three condition of water level (normal water level, maximum water level, and minimum water level). Thus, three-dimensional finite element analyses are carried out using ABAQUS 6.14.
