为了确保在复杂条件下钢筋混凝土水塔爆破拆除倒塌过程中的安全,在正式爆破拆除之前,利用计算机技术进行数字模拟变得尤为重要。讲述了在ANSYS/LS-DYNA软件平台下,对20 m高的钢筋混凝土结构的水塔在复杂环境下模拟其爆破倾倒过程,通过对模型的建立、计算以及后处理等过程,可以清楚地看到水塔在模拟倒塌过程中倒塌倾角及倒塌后堆积长度与时间历程的变化,且模拟结果与实际工程相吻合。
In order to ensure the safety of the reinforced concrete water tower under the complicated conditions of demolition and collapse, it is particularly important to use the computer technology to conduct numerical simulation before the blasting demolition. It is described that the 20 m high reinforced concrete water tower simulates the process of demolition and dumping in a complex environment under the software ANSYS / LS-DYNA. Through the process of model establishment, calculation and post-treatment, it can be clearly seen The collapse angle of the water tower during the collapse process and the change of the pile length and time history after the collapse, and the simulation results are consistent with the actual project.
