| 摘 要： | 首先运用遗传算法,在一定的初边值条件下通过对比试验实测值与解析解确定出导热系数与比热的函数值α(λ,c,ρ),再利用已确定出的系数α,通过遗传数值法计算值与实测值比较,进而确定出等效导热系数λ与比热c。

| Abstract: | It is very important to accurately and quickly ascertian the thermal parameters of the frozen soil in the frozen construction progress.Firstly the value which is the function of the thermal conductivity and specific heat is ascertained through comparing the data with the analytical solution under certain boundary condition and initial values.Then the thermal conductivity and the specific heat are calculated through comparing the genetic finite element value with the experimental value. |
