事故多发路段改造提升设计与关键技术研究

Research on the design and key technology of upgrading accident-prone road sections

为了更好优化事故多发路段的道路状况,梳理、分析某改造提升公路工程的优化提升措施和改造设计方案。在分析探讨某工程基本情况、路线情况、路基情况和桥梁涵洞损坏程度的基础上,提出原有公路改造的设计方案。同时,根据设计方案的总体思路,分析探讨公路改建设计过程中应遵守的原则与技术标准。最后,对路线线形优化、陡坡路堤处理和深挖路堑防护等设计措施进行分析。项目的设计方案满足使用功能要求和投资预算。

In order to better optimize the road conditions of accident prone sections,sort out and analyze the optimization and improvement measures and renovation design schemes for a certain highway renovation project.Based on the analysis and discussion of the basic situation of the project,route conditions,roadbed conditions,and the degree of damage to bridges and culverts,a design plan for the renovation of the original highway is proposed.Meanwhile,based on the overall design concept,analyze and explore the principles and technical standards that should be followed in the process of highway reconstruction design.Finally,an analysis and introduction of design measures such as route alignment optimization,steep slope embankment treatment,and deep excavation road cut protection are presented.The design scheme of this project meets the functional requirements and investment budget.
