摘要： 以上海市翔殷路越江隧道工程为背景，对隧道周围土体进行动三轴试验，建立了隧道的荷载结构模型，分析了不同工况下的荷载变化情况，并基于试验得出的抗力系数，计算出各种工况下隧道主体结构的内力.结果表明：在核爆荷载作用下，土体的弹性模量和抗力系数得到显著提高；通过设置防护门，可以显著提高结构的抗核爆性能；在6级人防荷载作用下，隧道主体结构能够满足承载力要求.

Abstract: Based on the river-crossing tunnel of Xiangyin road in Shanghai，elastic modulus and resistant coefficient of soil were analyzed with dynamic tri-axial test under the condition of nuclear blast. The results show that two parameters increase significantly. Load and structure model was performed and internal force of tunnel  was calculated in different load conditions. The results indicate that protective door can improve the anti-nuclear blast capability of tunnel structure and the river-crossing tunnel can meet the requirement of bearing capacity under grade-6 civil defense load.

Key words: river-crossing tunnel, nuclear blast, dynamic tri-axial test, elastic resistant coefficient, protective door
