This thesis contrasts and analyses the different calculation - method, and improves the genetic algorithm in the parameter inversion of the rock and soil engineering. the strategies are mainly in the following three aspects : 1, new searching way is compositely searching genetic algorithm which is made up of the acceleration method and genetic algorithm when it partially calculates in the later time ; 2, index function is inducted in gengetic operators, at the same time repeated select and double exchange pool are used ; 3, splicing crossover, which reserves some new evolution factions, improves authority function accaunting the capabilities and kinds
本文對優化演算法中不同求解方法進行對比分析，針對遺傳演算法在巖土工程參數反演運算中進行了改進，改進的策略主要集中於三個方面： 1 、提出了在遺傳演算法中融入形加速法的改進方法? ?復合遺傳搜索法； 2 、針對遺傳運算元的選擇策略，引入指數適值方法，設置雙交換池，提出了重復篩選法； 3 、加強對劣勢種群的內部優良信息的遺傳功能的改進，引入權函數，擴大可交叉運算元的種類，保留各運算元的進化功能，提出了融合交叉運演算法。
