- Abstract:
- The thermal parameters are obtained , which have great influence on computation of temperaturefield of concrete dam.Usually the parameters are obtained from test or empirical formula.Because thermalcharacter of conerete and external environment’s complexity and the experimental limitation, it is very difficultto obtain a more precise parameters . In order to solve the problem,in this paper, by using micro-genetic algo-rithm in back analysis of the thermal parameters of concrete dam,toge ther with finite element solution theoryfor three-dimensional transient temperature field,we worked out a back analysis program for three-dimensionaltransient temperature field with micro-genetic algorithm,and engineering examples are given.Result showsthat micro-genetic algorithm to reduce the computation than SCA,and to restart maks the population have andideal diversity,which to avoid the premature phenomenon.
