| 摘 要： | 为研究爆炸条件下土中钢油罐受力特性,根据模型几何相似理论,研究了地面爆炸作用下土埋钢油罐的受力特性.在核爆压力模拟器内进行了土埋钢油罐模型的爆炸压力加载试验,采用动态测量技术,得到了不同埋土表面超压下土埋钢质圆柱壳模型的动压力、动位移和动应变数据.试验表明,作用在土埋圆柱壳上的动压呈现底部动压峰值较大的特点,柱壳则为动态弯曲应力状态.其中,环向应变在底部为拉应变,侧部和顶部为压应变,纵向应变在壳体顶部和底部均为压应变,侧部为拉应变.在试验加载范围内(地面超压为0.09～0.88 MPa),应变仍在材料弹性变形范围内.

| Abstract: | Based on the geometric similarity theory,the force characteristics of the soilembedded steel tank were analyzed.A loading experiment was carried out in the pressure simulator of nuclear explosion.The dynamic pressure,the displacement and the strains of the column steel model under different ground excessive pressures were obtained by using dynamic measuring techniques.The results show that the peak value of the dynamic pressure at the bottom of the soil-embedded column shell is the biggest,and the column sh... |
