Thermal Analysis of Mass Concrete of Gravity Dam Using Finite Element Method

Abstract

Mass concrete is used extensively in modern construction, particularly in hydraulic and hydroelectric projects.
Every year, more than 10 million cubic meter of mass concrete is poured in hydraulic and hydroelectric
engineering in India. Furthermore, mass concrete is frequently used in harbour engineering and large machine
foundations In this study, the various lift heights and lift intervals were determined in order to attain the
minimal temperature inside the mass within the allowable limit. Lift heights of 1m are used for various lift
intervals of 120hr, 144hr, and 168hr. The maximum temperature in the concrete mass are computed using
conventional methods. Heat generation and temperature field in mass concrete are studied using Ansys
software, which employs the finite element approach to solve the problem. The application allows you to
check the temperature of different concrete ages. It is feasible to check the temperature for various concrete
qualities using software by analyzing them on different concrete days. As a result, it was feasible to conclude
that the concrete's qualities have a direct impact on the temperature evolution phenomenon.
