极端气候下交通基础设施脆弱性研究综述
Review of Research on Vulnerability of Transportation Infrastructure to Extreme Climatic Conditions
摘要
Abstract
The intensifying global climate change is increasingly affecting the operational performance of existing transportation infrastructure due to extreme climatic events such as heavy precipitation,high temperatures,low temperatures,and drought,leading to severe damage.Meanwhile,with the further implementation of the strategy of building China with a strong transportation network,a significant number of new transportation infrastructure projects are being constructed in harsh environments,posing unprecedented challenges to the functionality,durability,and maintenance management of these new facilities.The characteristics of extreme climate loads include rapid and unpredictable variations,often accompanied by coupled effects of multiple disasters,rendering the mechanisms of damage to transportation infrastructure under their influence highly complex.To ensure the safety and effectiveness of transportation infrastructure under extreme climatic conditions,Chinese and international research on extreme climate and multi-disaster coupling was studied,and the research progress on spatiotemporal evolution of extreme climates and multi-disaster coupling effects was systematically reviewed.The impact mechanisms of multiple disasters on engineering structures were sorted out.Based on this foundation,the characteristics of extreme climate impacts were defined,and disaster prevention and reduction design principles for transportation infrastructure during the design,construction,and maintenance phases were proposed.Furthermore,methods for assessing multi-disaster risks to transportation infrastructure under extreme climatic conditions were comprehensively summarized,and future research was prospected,highlighting the importance of utilizing artificial intelligence and machine learning technologies for rapid prediction and assessment of extreme climatic disasters and analyzing changes in the performance of transportation infrastructure systems throughout their whole life cycle.This research provides valuable references for the disaster-resistant design,performance assessment,and resilience enhancement of transportation infrastructure such as bridges,roads,and tunnels under extreme climatic conditions.关键词
