基于滑坡案例库的铁路选线辅助决策方法研究

Study on Auxiliary Decision-making Method for Railway Route Selection Based on Landslide Case Base

为了将以往工程案例更好地应用于土质边坡滑坡灾害的选线决策中。通过查询相应的历史资料,建立铁路沿线土质边坡历史滑坡灾害案例库,将其用于某山区铁路滑坡区域选线方案的辅助决策。选取6个控制因素和2个诱发因素作为指标,对土质边坡滑坡灾害进行标准化研究,并运用熵权法求取各个因素指标的权重,运用灰色关联分析法将目标案例与案例库中的既有案例进行匹配,根据匹配案例的选线措施结合项目实际情况进行修正,以辅助目标案例选线决策。最后对滑坡实例进行分析,结果表明,匹配案例与目标案例相似度高达0.9100,且专家建议和匹配案例的整治措施有一定的相似性,证明了该方法的合理性。

In order to better apply the previous engineering cases to the line selection decision of soil slope landslide disaster.This paper queries the corresponding historical data and establishes the case base of soil slope historical landslide disaster along the railway,which is used for the auxiliary decision of railway landslide regional route selection scheme in mountain railway.This paper selects six control factors and two factors as indicators,standardization of soil slope landslide is studied,and the use of entropy method to calculate the weight of each factor,using the grey correlation analysis method in the target case and putted forward both case matching,according to the matching case modification of line selection measures in combination with the practical situation of the project,to assist the target case line selection decisions.Finally,through the case analysis,the results show that the similarity between the matching case and the target case is as high as 0.9100,and there is a certain similarity between the expert advice of the target case and the control measures of the matching case,which proves the rationality of the method.
