基于层次分析法划分狮子洋隧道水文地质单元的研究

摘要

Based on qualitative sectioning of tunnel area,various evaluating indicators are determined from the influencing factors for division of hydrogeological unit and the weighting of each evaluating indicator is determined by analytic hierarchy process.Then each tunnel section is evaluated using fuzzy comprehensive evaluation method.The adjacent sections belonging to the same level are classified into a hydrogeological unit.Combined with the practical engineering of Shiziyang Tunnel,a theoretical method for division of hydrogeological unit is thus provided.%在对隧道研究区定性分段的基础上,从影响水文地质单元分区的因素入手,确定各评价指标,利用层次分析法确定了各评价指标的权重,采用模糊综合评价方法,对隧道区各段进行了评价,将属于同一等级的相邻段划分为一个水文地质单元。结合狮子洋隧道实例,为水文地质单元的划分提供了一种理论方法。
