摘要
利用盐宜高速铁路工程地质勘察资料,综合收集多方面资料,基于研究区地质条件特性选取9个因子作为评价模型的基本变量,建立研究区地质条件评价的三级层次分析模型。采用层次分析法,通过评价因子量化分级和权重,对盐宜铁路工程地质条件进行综合评价,以计算所得各单元总值为依据采用自然断点法(Natural Breaks),将研究区分为良好、中等、较差和差四个等级。目前,该区域缺乏系统性的地质条件评价,本研究较好地将AHP用于研究区地质条件评价工作,其结果也可为拟建盐宜铁路区域的设计及施工、灾害隐患排查和防治提供基础依据和技术参考。
This article utilized engineering geological survey data from the Yancheng-Yixing High-speed Railway,comprehensively collects various data,selects 9 factors as the basic variables of the evaluation model based on the geological conditions of the study area,and established a three-level analytic hierarchy process model for evaluating the geological conditions of the study area.Using the Analytic Hierarchy Process,a comprehensive evaluation of the engineering geological conditions of the Yancheng-Yixing High-speed Railway was conducted by quantifying and grading evaluation factors and weighting them.Based on the calculated total values of each unit,the study was divided into four levels:good,moderate,poor,and bad using the Natural Breaks method.At present,there is a lack of systematic geological condition evaluation in the region.This study effectively applies AHP to the geological condition evaluation of the research area,and its results can also provide a basic basis and technical reference for the design and construction,disaster hazard investigation and prevention of the proposed Yancheng-Yixing High-speed Railway area.
