工程结构在武器效应作用下的安全度分析对于结构设计、防护性能评价以及武器效能检验等都十分必要。由于防护结构处于战场环境,无论外部荷载还是结构响应都受到大量随机因素影响,所以引入概率方法进行结构防护性能分析,使问题更好地反映了客观实际。本文应用结构安全度及结构动力分析有关原理和结论,简化作用于结构上核爆荷载与结构承载能力的分布规律,模拟计算阵地范围内工事口部结构安全度和防护效率。并以此对不同抗力等条件下的计算结果进行效能费用分析,以期得出阵地工事防护门设置以及与劲部动被复段级配的“最佳抗力”指标。文中同时给出了战术核袭击瞄准中心不在工事中心情况时,对工事
The safety analysis of engineering structure under the effect of weapon is very necessary for structural design, evaluation of protective performance and weapon effectiveness test. Due to the fact that the protective structure is in the battlefield environment, both the external load and the structural response are affected by a large number of random factors. Therefore, the introduction of the probabilistic method to analyze the structural protection performance makes the problem better reflect the objective reality. In this paper, the principles and conclusions of structural safety and structural dynamic analysis are applied to simplify the distribution of nuclear explosive loads and structural load-carrying capacity of structures, and to simulate the safety and protective efficiency of the structures at the mouths of structures. Then, the author analyzes the calculation results under different conditions of resistance and so on, in order to obtain the “best resistance” index of the setting of protective gates in front of the fortifications and the grading of each section with the strength of bulldozers. The article also gives the tactical nuclear attack aiming center is not in the case center, the fortifications
