摘要

基于层次分析法、专家调查法和模糊评价法

对风积沙隧道塌方风险源因素进行识别

提出了工程地质因素、水文地质因素和施工设计因素三大类风险源。分析了各类风险源下具体风险因素的权重以及评价集

结合神木一号风积沙隧道的具体特点

对其塌方风险进行了评价。研究表明:影响风积沙隧道塌方风险的主要因素是施工设计因素

而施工设计因素中

超前支护类型这一二级风险因素又是风积沙隧道塌方与否的决定性条件。

Abstract

Based on the analytic hierarchy process（AHP）

the expert survey method and fuzzy evaluation method

the risk source factors of strata collapse for aeolian sand tunnel are identified

and the three categories of risk source including engineering geology

hydrologic geology and construction design are proposed.Analyzing the specific weights of risk factors and evaluation set under all different risk sources

combining the specific characteristics of Shenmu No.1aeolian sand tunnel

the risk of surrounding rock collapse is evaluated.Research shows that:construction design is the main risk factor

which influences the aeolian sand ground collapse

and for the level 2risk factors under construction design factor

the advanced support type is a decisive condition

which decides whether the aeolian sand tunnel collapses or not.
