Comparison of Design and Analysis of Concrete Gravity Dam

Abstract: Gravity dams are solid concrete structures that maintain their stability against design loads from the geometric shape, mass and strength of the concrete. The purposes of dam construction may include navigation, flood damage reduction, hydroelectric power generation, fish and wildlife enhancement, water quality, water supply, and recreation. The design and evaluation of concrete gravity dam for earthquake loading must be based on appropriate criteria that reflect both the desired level of safety and the choice… Show more

“…The statistical model assumes that the components are completely independent and may not match the actual situation [5]. At present, the most common statistical 2 Mathematical Problems in Engineering models are based on regression methods such as the multiple linear regression (MLR) [6], stepwise regression (SR) [7], principal component regression (PCR) [8], and partial least squares regression (PLSR) [9]. By gradually screening regression factors of MLR models, SR models obtain regression coefficients at a certain significance level, results more accurate than those obtained by the general least square method.…”

“…The failure modes of a concrete gravity dam may be due to overturning, sliding or crushing [1]. According to Ali et al the overturning or rotational failure about the toe will occur when the point of intersection of the dam base and the line of action of the resultant of all forces acting on the dam lays downstream of the toe i.e.…”

“…According to Ali et al the overturning or rotational failure about the toe will occur when the point of intersection of the dam base and the line of action of the resultant of all forces acting on the dam lays downstream of the toe i.e. outside of the base [1]. On the other hand, crushing failure may take place if the inherent strength of the dam material fails to withstand the stresses produced due to various loading.…”
