摘要
基于Rockfall对岩质边坡的落石落距进行了模拟,同时在分析落石落距的影响因素研究中,引入正交试验法,以落距为评价指标,将影响落石落距的五种因素取四种水平进行五因素四水平的正交试验模拟分析。结果表明,坡高是影响落距第一因素,其次是坡角,回弹系数,速度和质量;可为科学建立落石落距的预测系统,以主要影响因素为输入参数,建立落石落距的预测样本集,准确判断落石的最终落距提供依据。
The authors simulated fall rock drop distance of a rock slope based on the software Rockfall. During the study of fall rock drop distance influence factors, introduced the orthogonal test. Taking the drop distance as the assessment index, carried out 4 levels orthogonal tests for 5 factors influencing fall rock drop distance orthogonal test simulation analysis. The result has shown that the first drop distance influence factor is slope height, then slope angle, coefficient of elastic recovery, velocity and mass. On this basis can establish a scientific fall rock drop distance prediction system. Taking the main influence factors as input parameters, establish fall rock drop distance prediction sample set, and provide foundation for accurate judgment of final fall rock drop distances.
