摘　　要：针对液氨泄漏事故严重程度的不同,开展相应的应急救援有利于控制事故影响范围和减少事故损失。统计发现绝大多数液氨安全事故是由于液氨储罐及其附件等破裂造成氨气泄漏所致。分析了影响液氨泄漏事故严重度的主要因素,并进行影响因素严重度等级划分,建立了液氨泄漏事故后果严重性可拓综合评价模型,举例说明了这种评价方法的可行性和合理性。For different severity of liquid ammonia leakage accident, carrying out appropriate emergency rescue benefits to control influence scope of the accident and reduce accident losses. It is found that the vast majority of accidents is due to liquid ammonia leakage caused by liquid ammonia storages and their accessories rupture according to statistics and analysis. Then based on the analysis of influence factors of liquid ammonia accidents and severity grade of influence factors, extensible assessment of consequences severity about liquid ammonia leakage accident is established. Finally, an example is given to illustrate the feasibility and rationality of the assessment method.
