基于分层遗传算法的土钉支护方案研究

STUDY ON THE SOIL-NAIL PLAN BASE ON THE HIERARCHICAL GENETIC ALGORITHMS

土钉支护方案的选择,对土钉设计十分重要。现行的土钉支护设计一般由工程类比或设计经验确定,可能造成材料浪费和安全隐患。将分层遗传算法应用于土钉支护方案的优化中。工程实例计算证明,经分层遗传算法优化后,在满足安全系数的前提下,土钉支护方案造价有所降低,优化效果良好。

The choice of the soil nailing plan is evey important to the soil nailing design. The current design of soil nailing generally determined by experience, may result in material waste and safety problems. This paper will hierarchical genetic algorithm is applied to soil nailing layout optimization. Project example calculation shows that optimized by the hierarchical genetic algorithm, to meet the security requirements, the soil nailing program cost decreased to optimize good results.
