公路隧道安全性评价范围及技术要点解读

Interpretation of Highway Tunnel Safety Audit Scope and Technical Key Points

摘要: 公路隧道安全性评价是保障隧道交通安全的重要技术手段。但是由于现行标准中隧道安全性评价范围及技术要求不够具体，造成小部分项目安全性评价报告质量不能满足实际需要。本文在《公路项目安全性评价规程》(T/CECS G: E10-2021)编制过程中，总结相关科研成果及工程实践经验，从隧道路段的线形、交通安全设施、机电设施、应急救援等方面，明确了工程可行性研究阶段、设计阶段、交工阶段及运营阶段中公路隧道安全性评价的范围及技术要点。本文作为《公路项目安全性评价规程》(T/CECS G: E10-2021)隧道部分条文规定的解读，阐述了与《公路项目安全性评价规范》(JTG B05-2015)相关条文的差异，明确了修订条文和新增条文的内容、目的、原因、背景等，划分了安全性评价与设计和质量管理等相关工作界面，目的是通过解读帮助标准使用人员和评价人员更好理解和运用《公路项目安全性评价规程》(T/CECS G: E10-2021)隧道部分条文，把握评价重点内容、评价范围和评价深度，有效地提高公路隧道安全性评价工作的质量，进而提升公路隧道的安全水平及运营效率。文章成果写入《公路项目安全性评价规程》(T/CECS G: E10-2021)、贵州省公路项目安全性评价指南(2020-141-022)。

Abstract: Highway tunnel safety evaluation is an important technical way to guarantee traffic safety. How-ever, the scope and technical requirements of tunnel safety evaluation in the current standard are not specific and detail enough, resulting in the quality of some evaluation reports could not meet the practical needs. The authors summarize the recent research achievements and engineering practice experience during drafting Technical Specifications for Highway Safety Audit (T/CECS G: E10-2021) (TSHSA). In TSHSA, the authors have put forward the scope and main technical points of road tunnel safety evaluation in the feasibility stage, design stages, pre-opening traffic stage and operation stage of highway, including tunnel alignments, traffic safety facilities, mechanical and electrical facilities, emergency rescue, etc. This paper is interpreted as the tunnel part of TSHSA. The paper explains the differences between TSHSA and the relevant tunnel provisions of highway safety audit (JTG B05-2015), has cleared about the purpose, cause, background, etc., of the revised provisions and the new provisions, divides the evaluation interface with the design and quality control related work. The paper’s purpose is to help the user of auditors and readers understand, grasp the evaluation scope, key contents, and evaluation depth, which will be to guarantee effectively the quality of highway tunnel safety evaluation and improve the safety level and operational efficiency of the highway tunnel. The conclusions of this paper will be written into TSHSA and Guizhou Provincial Highway Safety Audit Guidelines (2020-141-022).
