摘　　要：作者曾对烟囱模型在其基底受到横向冲击作用下的破坏进行了试验研究［２］ 。本文的目的在于研究烟囱模型在竖向冲击振动下的破坏现象与地震破坏现象是否相似。实验结果表明： 在竖向冲击振动下，烟囱只能产生一道环形裂缝， 裂缝的位置与输入波的频率有关。同时，Fracture test of chimney models subjected to horizontal shock at the bottom of models was reported in reference\ To study the fracture phenomena of chimney models subjected to vertical shock is the purpose of this paper The test result is that only one circle crack appeared in the chimney models and the level of the crack has a connection with the ratio of input wave frequency to the natural frequency of chimney model Multicrack was hardly to be found in this test

关 键 词：竖向冲击 环形裂缝 振动破坏试验 烟囱
