摘要： 在进行大体积混凝土温度应力以及温度场有限元计算的时候，经常使用绝热温升的数学表达式，所以要对测定的数据进行数学拟合，求出绝热温升的经验公式，因此我们需要拟合的公式尽可能的符合测定的数据。在本文中则给出运用遗传算法进行参数的拟合，以期达到较好的拟合效果，使进行计算达到更加精确的目的。本文采用C语言进行编程，使得庞大的计算过程的时间比较节省，程序更加通用。

Abstract： When we calculate thermal stress and temperature field for bulk concrete with FEM, we often adopt the mathematical expression of adiabatic temperature rise. In this case, we need to conduct numerical simulation on test data in order to find the empirical equation of adiabatic temperature rise. And we hope that the simulation equation is as the same with test data as possible. In this paper, anther show how to use genetic algorithm to simulate coefficients and to get the expected simulation effect , eventually to gain the intended purpose of accurate calculation. Author adopts C computer language to program, which shortens the time spent on the demanding calculation and makes the program a more applicable.
