摘要
根据土石坝沉降规律 ,以时效量作为基本影响因子 ,运用遗传算法基本原理 ,建立了土石坝沉降的遗传算法模型 .并采用遗传算法的改进措施 ,同时从优化模型和土石坝沉降规律出发确定了决策变量的定义域 ,减小了搜索范围 ,提高了搜索效率 .
Applying basic theory of genetic algorithms, we establish genetic algorithms model of earth-rock dam settlement according to the feature of the earth-rock dam settlement in which we use aging amount as basic effect factor. Improved basic genetic algorithms in the process of model building is adopted. The definition domain of decision variable is determined according to the optimal model and the feature of the earth-rock dam settlement,so the search range is reduced and the search efficiency is improved.
