Abstract:

A computer program for the computation of the unsteady state temperatures that develop during the construction of a concrete dam in layers lifts is described. Information pertaining to the following ambient and structural conditions and thermal properties is necessary for a computation ambient air temperature and foundation temperature, concrete temperature at time of placement, lift thickness, number of days between lifts, and adiabatic temperature rise and thermal diffusivity of the concrete. The computation may be continued for fifty lifts. The computation is based on a numerical procedure for the solution of the heat flow equation for one dimension. The space interval is one-quarter thickness of a lift, and the time interval is one-quarter day. The program is written for the basic IBM-650 computer with a 2000-word drum.
