摘要/Abstract

摘要： 为系统了解可燃气体爆炸灾害效应研究成果,基于长直空间内可燃气体爆炸的特点,总结灾害后果评估的一般流程,综合梳理长直空间内可燃气体爆炸荷载的理论计算模型、试验及数值模拟结果,探讨可燃气体爆炸作用下结构的动力响应以及可燃气体爆炸对人员伤亡和结构毁伤后果评估等国内外研究进展。结果表明:现有可燃气体爆炸荷载经验式大多有各自的适用范围,不具有通用性,长直空间内可燃气体爆炸作用下结构动力响应的试验数据较少;现有对压力容器的研究成果对长直空间动力响应研究价值有限,爆炸冲击波作用下人员和建筑物的伤害标准还不统一。

Abstract: In order to systematically study research results on disaster effect of combustible gas explosion, general steps for disaster consequence assessment were summarized based on characteristics of such explosion in long straight space. Then, theoretical calculating model, experimental research and numerical simulation results of combustible gas explosion load were discussed, and research progress on structural dynamic response and consequence assessment of explosion was explored. The results show that most of existing empirical formulas of gas explosion load, with their own range of application, are not universal. Test data concerning dynamic response of explosion structure in long straight space are few, and research results on pressure vessels are of limited value to study it. Moreover, standards of building and personnel damage under explosion shock wave have not been unified.

Key words: long straight space, combustible gas, explosion load, consequence evaluation, dynamic response
