摘要

摘要: 为研究核电厂主蒸汽管道断裂后对钢衬板加强墙体的甩击效应，开展了单钢衬板-混凝土（Half Steel Plate Reinforced Concrete，HSC）靶板抗冲击试验，分析了HSC板的损伤机制和破坏模式。采用LS-DYNA有限元软件开展了试验仿真分析，基于试验结果完成了仿真模型的验证工作。进一步，基于已验证的仿真模型，建立了高能管道甩击钢衬板加强核电厂房墙体的全尺寸精细化仿真模型，分析了不同墙体设计参数、管道甩击参数对墙体损伤的影响。研究结果表明：管道弹体冲击试验可以较好地揭示HSC板的损伤破坏特点，获取有效的静态损伤和时程响应数据；建立的有限元分析方法能够对试验结果进行较准确预测，在全尺寸模型中，采用钢衬板置于背侧加强的墙体抗冲击性能更优，将栓钉和钢筋网焊接后则会进一步降低冲击力及墙体损伤。随着甩击速度和着靶角度的增加，墙体的侵彻深度也逐渐增大，在给定的管道甩击参数范围内，墙体最大侵彻深度为0.42 m，未发生贯穿破坏。

Abstract: This study investigates the impact effects of main steam pipe whip on the half steel plate-reinforced wall of a nuclear power plant through a series of impact tests. The damage mechanisms and failure modes of the high-strength concrete （HSC） plates were analyzed in detail. Simulation analysis using LS-DYNA was conducted， and the simulation model was validated against the experimental results. A full-scale， refined simulation model for high-energy pipeline impact on the steel plate-reinforced wall of a nuclear power plant was established using the validated simulation parameters. The simulation explored the effects of various wall design parameters and impact conditions on wall damage. The results indicated that the pipeline projectile impact test effectively revealed the damage and failure characteristics of the HSC plate， providing valuable static and time-history response data. Finite element analysis accurately predicted the experimental outcomes. In the full-scale model， the impact resistance of the steel plate-reinforced wall was superior. The impact force and wall damage were further reduced when the studs and steel mesh were welded. An increase in speed and target impact angle resulted in a gradual increase in the penetration depth of the pipe into the wall. Within the pipeline whipping parameters defined in this study， the maximum penetration depth of the wall structure was 0.42 m， with no occurrence of penetration failure.
