| 摘 要： | 运用动力分析软件LS_DYNA3D,采用任意拉各朗日-欧拉算法,分别对钢纤维喷射混凝土支护和无支护条件下抗常规爆炸的震塌过程进行了三维数值模拟,并将数值模拟结果与规范中其它支护类型在相同条件下的震塌落石速度进行对比.通过震塌剥落层速度的对比,量化说明了钢纤维喷射混凝土支护结构抗爆炸震塌的能力.

| Abstract: | The collapse process of the tunnel, which is reinforced by steel fibre shotcret and is not reinforced at the same rock class and same span condition respectively, is simulated with the arbitrary Lagrangian Eulerian method of LS DYNA3D under normal striking. By comparing the dropping velocity of collapse ceiling obtained from simulation with other lining systems present in the structural design codes for protective engineering, we can quantitatively study the ability of steel fibre reinforcing shotcret lining from a quantity view. |
