摘要
伴随着事故型爆炸、恐怖袭击和精确制导武器打击等威胁的增强,桥梁结构抗爆安全防护问题越来越受到人们的关注,而目前桥梁结构设计中还没有特别考虑抗爆及其安全防护问题.从爆炸荷载模型、桥面板和主梁抗爆与防护、墩柱及缆索抗爆与防护、桥梁水下抗爆、整桥结构抗爆与防护、桥梁爆炸易损性分析和韧性评估等8个方面较为详细地梳理了国内外研究现状以及取得的主要成果,归纳了各自存在的主要问题,并对未来主要研究方向进行了展望,以期对桥梁结构抗爆安全防护研究提供新的视角和一定的借鉴.
Abstract
The rising threat of accidental explosions,terrorist attacks,and precision guided weapon strikes has motivated increasing interest in the anti-explosion safety protection of bridge structures.However,these challenges have received inadequate attention in the current bridge-structure design process in China.This paper summarizes the research development and the main achievements,at home and abroad,of eight aspects:the explosion load model,bridge deck and main girder anti-explosion and protection,pier and cable anti-explosion and protection,bridge underwater anti-explosion and protection,whole bridge structure anti-explosion and protection,bridge explosive vulnerability analysis,and resilience assessment.The main challenges facing these aspects are identified.We then propose the main directions for future research,giving a new perspective and some reference for anti-explosion and safety protection research relating to bridge structures.
