APPLICATION OF PP METHOD BASED ON RAGA TO ASSESSMENT OF SAND LIQUEFACTION POTENTIAL
基于实码加速遗传算法的投影寻踪方法在砂土液化势评价中的应用

The assessment model of sand liquefaction potential is investigated using projection pursuit (PP) method with real-coding-based accelerating genetic algorithm (RAGA). The algorithm and the flowchart are proposed. The practical example shows that the PP method is feasible and effective to assess sand liquefaction potential,and the result is good. The model provides a possibility for visual evaluation on sand liquefaction potential.
