摘要
为了对某飞机洞库的抗层裂钢板进行有效地设计,基于层状介质中一维应力波的传播理论,提出了脉冲荷载作用下地下结构混凝土中应力历史的计算方法。通过实际算例研究了混凝土中应力波的传播规律,揭示了抗层裂钢板的作用机理。可为地下结构的抗层裂设计、施工提供参考。
In order to design effectively the spall-resistant steel panels of underground structure for hangar, the formulas d stress histories within underground concrete structures is presented under impulsive loads is presented, based on onedimensional theories for stress waves within layered structures. Through the numerical example, the stress histories within the concrete are studied and the mechanism of spall-resistant steel pand is also demonstrated. This can serve as a reference for spall-resistant design and construction for underground structures.
