摘要：灰色关联分析(GRA)常用于边坡稳定性影响因素的敏感性分析,从既有文献实例出发,就该算法原始数据无量纲化的7种不同处理方法对结果的影响展开探究;然后以贵州花鱼洞大桥贵阳岸某含软夹层边坡为工程背景,采用极差分析+GRA+层次分析(AHP)的复合算法对边坡受软夹层主要参数影响的敏感性进行分析计算。结果表明,原始数据无量纲化处理方法对敏感性分析结果影响较大,其中基于“中心化”处理方法的GRA分析结果与极差分析、AHP分析有关结果相吻合,所得结果更为可靠。由此可见,在理论研究及工程实践中,宜联合多种算法进行边坡敏感性对比分析,以确保结果的准确性。
Grey Relational Analysis(GRA)is commonly used for sensitivity analysis of factors affecting slope stability.Based on the examples of existing literature,the influence of 7 different processing methods of dimensionless original data on the results of the algorithm is explored.Then,taking a slope project with soft interlayer near the Guiyang bank of the Huayudong Bridge in Guizhou Province as the engineering background,a composite algorithm of range analysis+GRA+Analytic Hierarchy Process(AHP)is used to analyze and calculate the sensitivity of the slope to the main parameters of the soft interlayer.The results indicate that the non-dimensional processing method of raw data has a significant impact on the sensitivity analysis results.Among them,the GRA analysis results based on the“centralization”processing method are consistent with the results of range analysis and AHP analysis,and the obtained results are more reliable.It can be seen that in theoretical research and engineering practice,it is advisable to combine multiple algorithms for comparative analysis of slope sensitivity to ensure the accuracy of the results.
