摘要(Abstract):

烟囱是对竖向地震较为敏感的结构物。通过建立微斜正锥形直杆-基础-半无限弹性地基的力学模型,讨论了烟囱在爆破地震作用下竖向反应的行波分析方法,并结合实例给出了一种理论结合经验的求解方法.
Chimney is more sensitive to vertical seism. A mechaincal model of tilting regularcone straight pole-foundation-semi-infinite elastic fo undation is set up in the p aper. Thetravelling wave analysis method of chimney vertical response to blasting seism is discussed here,and a computational method of theory and experience is presented by example.
