摘要:
支挡结构在山区铁路、公路工程中应用广泛,但受地质、水文、技术、材料等因素及勘察、设计、施工、维护等环节的影响,安全问题时有发生,如何精准识别、评估、防控支挡结构的安全风险是道路工程领域亟需解决的技术难题。为此,本文基于中铁二院工程集团有限责任公司支挡结构安全风险识别、支挡结构极限状态设计、支挡结构安全性能提升的科学研究成果,介绍支挡结构安全风险量化识别、极限状态设计参数匹配优化、复杂环境支挡结构安全性能提升等支挡结构安全风险识别与防控技术,以期为山区道路支挡结构的安全风险识别和防控设计提供指导借鉴。
Abstract:
Retaining structures are widely used for railways and highways in mountainous areas. However, due to the influence of geological, hydrological, technical, material, and other factors and the activities of investigation, design, construction, and maintenance, safety problems often occur. How to accurately identify, evaluate, prevent and control the safety risks of retaining structures is a technical challenge that needs to be solved urgently in the field of road engineering. Therefore, based on research achievements on safety risk identification, limit state design and safety performance improvement of retaining structure of China Railway Eryuan Engineering Group Co., Ltd., this paper introduces the identification and prevention and control of safety risks for retaining structure, such as quantitative identification of safety risk of retaining structure, matching and optimization of limit state design parameters, safety performance improvement of retaining structure in a complex environment, etc., in order to provide guidance and reference for the design of identification and prevention and control of safety risk for retaining structures of mountain roads.
