摘要
瓦斯隧道在施工过程中面临众多复杂的风险,而且施工风险源具有复杂性、随机性和模糊性,目前的研究方法难以对其进行准确定量分析。笔者结合实际工程的施工,通过深入分析影响瓦斯隧道施工的风险因素,建立了施工风险评价指标体系,采用专家调查法和层次分析法确定了各级因素的权重,分析得出影响施工的主要、次方面,并运用模糊数学的方法,建立模糊评判模型,对瓦斯隧道施工风险评价指标体系中的单因素和整体进行评价,最终根据评价结果确定了瓦斯隧道的施工风险等级。通过对计算结果分析,该方法在瓦斯隧道的施工风险评价上具有适用性和可靠性。
Numerous and great risks will be encountered in the construction of gas tunnel,and these construction risk sources generally have complex,random and fuzzy characters. Because of these characters of the risk factors,it is difficult to analyze in an accurate and quantitative way. In this paper,an assessment index system of gas tunnel construction risk is established by combining the construction of an actual project and deep analyzing of the factors that influence the gas tunnel construction. The Expert Investigation and Analytic Hierarchy Process are applied to determine the weights of factors of each level,at the same time,the master and secondary aspects which affect the gas tunnel construction are acquired by analyzing the weights. And the fuzzy mathematics method is used to establish a fuzzy judgment model that can evaluate single factor and overall factors in the assessment index system of gas tunnel construction risk. Finally,the level of risk is determined according to the assessment results. The conclusions indicate that the method is applicable and reliable in the assessment of gas tunnel construction risk,which has some theoretical significance and practical value in order to improve the objectivity and accuracy of the gas tunnel construction risk assessment.
