摘　　要：为研究装配式复合墙结构在使用中承受动荷载作用的问题,将缩比试验模型置于核爆炸压力模拟坑中进行爆炸试验。给出2种不同接头形式的装配式复合墙结构缩比模型的4个试验结果,得到的冲击波波形曲线以及钢板(或扶壁柱)和混凝土表面的应变时程曲线,与单向厚板理论分析结果符合较好。通过观察和分析不同试验模型的动力特性以及破坏形式,验证了2种接头在设计爆炸冲击波荷载下的安全性,钢板接头模型相比扶壁柱接头模型延性更好,在冲击波的作用下的动力性能更优越。To investigate the mechanical behaviours of the assembled compound periphery structure under dynamic loads, their scale models were loaded in the nuclear explosion pressure simulation hole. There were two types of scale models with different joint styles. Results of the four test models were presented. The shaape of shock wave and the strain histories on the surfaces of steel plate （counterfort column） or concrete are obtained, which agrees with the one-way thick plate theory analysis results. Dynamical characteristics and failure modes of different test models were observed and analysed. It is validated that both the steel plate joints and the counterfort column joints are feasible under the designed shock wave load. It is al- so proved that the steel plate joints are more ductile than the counterfort column joints as well as better dynamic per/ormance subjected to blast wave.
