| 摘 要： | 该文对带有筏板基础和地下室的多层框架及框剪建筑物在遭受邻近地下隧道内爆炸冲击作用下的动力响应进行了分析研究。采用ABAQUS软件建立了考虑地基土和混凝土等材料非线性的隧道-土体-多层建筑耦合体系的三维数值模型，经与LS-DYNA模型结果的比较分析验证了该文所建体系模型的正确性和有效性。通过大量的算例分析，对隧道内爆炸冲...

| Abstract: | The dynamic response of three types of a multi-storey building(including a framed structure with raft foundation,a frame-shear wall structure with raft foundation,a framed structure with basement) under a blast loading generated by an in-tunnel explosion is investigated numerically.The ABAQUS software is used to establish a three-dimension tunnel-soil-multi-storey building coupling model considering the material nonlinearity of the concrete and soil.The accuracy and validity of the coupling model set up wit... |
