【摘要】：当前对高速公路隧道施工安全的重视度较高,而运营高速公路隧道的安全性重视不足。事实上每年在隧道内发生的交通安全事故不胜其数,大多数安全事故如果采取必要的措施完全是可以避免发生或减小损失的。因此进行高速公路隧道运营安全是必不可少且具有重要意义的。高速公路隧道具有交通容量有限、内部空间封闭、缺少自然采光、通风不良、内部环境单调等空间结构特性,在发生交通事故时有灾害扩大速度快、联络与逃生困难等特征。高速公路在运营期间发生多起重大隧道安全事故,造成了巨大的经济损失和严重的社会影响。而另一方面,高速公路隧道在运营一段时间后,其衬砌结构、围岩稳定性、隧道内附属结构等均发生一系列劣化作用,致使其运营安全环境出现一定的隐患,故开展高速公路隧道运营安全评价,为高速公路隧道行驶舒适性与安全性提供保障。本文基于现有对高速公路隧道运营安全评价的理论研究上,分析高速公路隧道运营安全影响因素及构建安全评价体系,同时采用区间数学理论耦合模糊综合评价法对高速公路运营安全进行评价,得到如下几点结论:(1)高速公路隧道运营系统是由司乘人员、车辆与隧道共同组建而成的一个“人-机-环境”复杂系统,其运营安全性能受多个要素共同决定,主要包括运营管理、隧道结构健康度、机电控制、防火、交通等几方面。任何一环出现问题均可能造成交通事故的发生。(2)影响高速公路隧道安全运营的因素繁多复杂,因此采用半理论半经验、定量与定性分析相结合高速公路隧道运营安全综合评价指标体系。高速公路隧道运营安全评价体系的构建遵循严密性、少而精与重点突出的原则。(3)由于在进行高速公路隧道运营安全评估时评价人员具有较大的主观性以及测试数据的不确定性,因而采用定值评估具有一定的局限性,区间数学评估法是将数据以区间值表示,更接近于工程实际。(4)基于区间数学理论与模糊综合方法对某高速公路隧道构建运营的安全模糊区间评价方法,采用中值法与区间法的评价结果为78.925,在考虑区间最值时其计算值为[0.64,0.71],对应安全等级表可知,该公路隧道运营管理的安全状况为中级及偏上,表明该公路基本能够安全运营,但某些方面存在一定程度上安全隐患,需要有针对性地做出相应的安全技术措施。
[Abstract]:The current construction safety of highway tunnel has higher degree of importance, and the operational safety of highway tunnel seriously insufficient. Traffic accidents occur each year in fact in the tunnel is numerous, the majority of accidents if necessary measures can be avoided to happen or reduce losses. So it is very essential and safe operation of expressway tunnel is of great significance. The highway tunnel has limited transport capacity, internal space, lack of natural lighting, ventilation, structural characteristics of internal environment such as monotonous space, has expanded quickly in the disaster occurrence of traffic accident, contact and escape difficult feature. A number of major freeway tunnel safety accidents during operation, causing the the huge economic losses and serious social impact. On the other hand, the highway tunnel in operation after a period of time, the The stability of surrounding rock in tunnel lining structure, subsidiary structures all have a series of bad effect, resulting in the safe operation environment of certain risks, so to carry out the operation of expressway tunnel safety evaluation, safety and comfort to provide protection for highway tunnel road. This paper is based on the existing theoretical research of highway tunnel operation safety evaluation. Analysis of the factors, the operation of expressway tunnel safety effect and construction safety evaluation system, and evaluation of highway operation safety by fuzzy comprehensive evaluation method using interval mathematical theory coupled to the following conclusions: (1) the operation system of highway tunnel by passengers, a "man machine environment" vehicle and tunnel joint the formation of the complex system, the safety performance of the operation by a number of elements of joint decisions, including operations management, tunnel safety, electrical control Fire, transportation and other aspects,. Any link problems are likely to cause traffic accidents. (2) factors affecting the safe operation of expressway tunnel are various and complicated, so the semi theoretical and semi empirical, quantitative and qualitative analysis of highway tunnel operation safety evaluation index system construction. Follow the strict evaluation system of tunnel safe operation of expressway, concise and focused principles. (3) the personnel evaluation has great subjectivity and test data in highway tunnel operation safety evaluation of uncertainty, so the evaluation value has certain limitations, interval mathematics assessment method is the data by the interval value, closer to in the engineering practice. (4) the safety evaluation method of fuzzy interval interval mathematical theory and fuzzy comprehensive method based on the construction of a highway tunnel operation, with the median Evaluation method and interval method was 78.925, in considering the interval when the calculated value is [0.64,0.71], corresponding to the security level table, safety management of the tunnel for intermediate and partial, shows that the highway can basically safe operation, but some aspects exist to a certain extent security risks, the need for the to make the corresponding safety measures.
