混凝土拱座空心立柱水压爆破数值模拟研究

Study on Water Pressure Blasting of Reinforced Arch Seat and Hollow Pillar in Numerical Simulation

利用非线性动力有限元程序LS-DYNA建立了钢筋混凝土结构水压爆破的数值计算模型,通过流固耦合算法,对水压爆破的作用机理和作用效果进行了初步的探讨,得出了在钢筋混凝土结构数值模拟中对水压爆破切口的处理方法。

A numerical calculation model of water pressure blasting of reinforced concrete structures was established by the Nonlinear Dynamic Analysis finite element program LS-DYNA.The mechanism and effect of water-pressure blasting were primarily discussed and blasting cut processing method in a water-pressure blasting simulation was confirmed through fluid-structure interaction algorithms.
