重大工程设施抗爆韧性设计的思考

Reflection on Anti-Explosion Toughness Design in Major Engineering Facilities

分析了工程设施抗爆韧性设计的必要性,提出了重大工程抗爆韧性的概念与设计目标。针对民用关键基础设施、军事防护工程,从提高鲁棒性、降低间接损失、迅速恢复等方面讨论了相应的韧性实现技术。结合韧性与经济性关系,建立了基于预期总损失与工程总价值之比的韧性指数计算模型,综合考虑韧性指数与建设、恢复成本,可用于韧性设计方案决策优化。最后提出发展建议,包括加强针对重大工程抗爆韧性的技术支撑体系研究;加快工程抗爆韧性定量评估方法研究;加快重大工程抗爆韧性数据决策平台建设;选择典型重大工程并开展抗爆韧性设计示范应用,推进相关标准规范制定。

This paper analyzed the necessity of antiexplosion resilience design for major projects,proposing the concept of anti-explosion resilience and design objective,based on which,corresponding resilience realization techniques concerning robustness improvement,decrease of indirect loss,and fast recovery were discussed for key civil infrastructures and military protection engineering.Moreover,it established a calculation model of resilience index based on the ratio of expected total loss to total project value,integrating the relationship between resilience and economy.Considering the resilience index and construction and restoration costs,it uesd the model to optimize the decision of resilience design program.Furthermore,it recommended development proposals,including strengthening antiexplosion resilience investigations on technic-support system of major projects,accelerating the research on resilience evaluation method of engineering anti-explosion toughness,accelerating the construction of data decision platform for anti-explosion resilience of major projects,and selecting major projects and conducting demonstration applications of anti-explosion resilience design to promote the development of relevant specifications.
