| 摘 要： | 改进了进化遗传算法，提出了新的交叉算子和变异算子，使之具有更好的全局收敛能力。砂土液化是一种危害极大的地震破坏现象，其影响因素很多，选择地震烈度、砂土粒径、相对密度、标贯击数和有效正应力为判据，利用改进了的进化遗传算法建立了砂土地震液化的判别模型。与液化情况比较表明，改进进化遗传算法应用于砂土地震液化的判别效果良好。

| Abstract: | Based on Darwin's theory of evolution,new operators of crossover and mutation are presented in modified evolution genetic algorithm(EGA),which makes it obtain better global convergence. Liquefaction of sand during earthquake is a kind of greatly dangerous hazard and has relation to many facts.Using modified evolution genetic algorithm ,discrimination model is established according to earthquake intensity,soil diameter,relative density ,standard penetration value,effective normal stress.Compared with the field conditions, the model performs well in discrimination of liquefaction of sand. |
