摘要
本文根据塔式容器的结构地震荷载计算和地震破坏的经验，建立了塔式容器的一种震害预测方法，该方法以塔式容器地脚螺栓的抗拉强度和根径确定抗震系数，通过抗震系数确定塔式容器相应的破坏等级，简单易行，文中用此方法对大连石化公司的塔式容器进行了震害预测，初步验证了该方法的可靠性．
A kind of method for forecasting earthquake damage to the tower vessel is established in this paper,based on the calculation of the seismic load on tower vessel and the experience of tower vessel during earthquakes This method defines the anti_seismic coefficient in line with tensile strength and root diameter of the tower vessel foundation bolt,and then determines the relevant destructive grade of the tower vessel according to the anti_seismic coefficient This kind of method is simple and easy to use Earthquake damage to tower vessel in Dalian petrochemical company is forecasted using the suggested method The reliability of this method has been preliminarily tested and verified
