天津软土场地地震动特性对高层建筑物的影响

Influence of soft land seismic dynamic characteristics on high-rise building in Tianjin

随着天津经济的大发展,大量高层建筑迅速崛起.与此同时,针对天津地区大范围软土属于抗震性能最差的一类,在软土场地上的高层建筑极易遭受震害这一特点,结合天津市中心地区某工程场地的地震反应分析,着重论述了天津软土场地地震动特性对高层建筑物的影响,并指出了应做进一步探讨的问题.

With a high speed development of the economy in Tianjin,plenty of high-rise buildings appear promptly.The large scope of soft soil in Tianjin has the worst anti-seismic characteristics, and the high-rise building on the soft site is apt to suffer the damage of earthquake.The influence of the soft land seismic dynamic characteristics on the high-rise buildings in Tianjin is discussed emphatically in the light of an analysis of the seismic reaction for an engineering site in a central area in Tianjin. And some problems that should be discussed further are put forward.
