摘　　要：城市中的单建掘开式人防工程一般采用成层式结构,如何对成层式结构进行优化使其在满足主体结构跨度要求条件下具有良好的防护能力、便于施工且经济合理成为人防工程科研亟待解决的重要问题。通过4个支撑式薄板夹层结构模型野外化爆试验研究,观察到了遮弹板、钢纤维混凝土薄板以及支撑条的破坏现象,从而得出了支撑式薄板夹层结构的破坏机理以及支承间距变化对支撑式薄板夹层结构破坏形态的影响等结论。试验结果为支撑式薄板夹层结构在地下工程中的应用提供了一定的参考。Based on the blast loading test on the 4 thin plates Sandwich Structure with braced,failure phenomenon of shielded structure,steel fiber concrete plates and braced strip had been measured.It is found that failure mechanism of thin plates Sandwich Structure with braced.Rupture appearance of this structure is obtained,which is being affected by space changes of braced strip.The experimental research supplies a reference basis for applications of thin plates Sandwich Structure with braced in underground structures.
