【摘要】 回顾了云南近年来发生的几组震群型地震中"续发地震"经济损失评估的基本情况、评估方法与结果,提出了对"续发地震"经济损失评估方法与结果的一些认识:(1)用"扣除总损失"的方法评估"续发地震"经济损失更易操作;(2)当震级相当时,"续发地震"经济损失一般不超过"前发地震"经济损失;(3)"续发地震"损失评估时,可在规范给定的损失比范围内适当提高损失比,以反映部分建筑"破坏等级饱和"而实际损失可能增加这一事实。更多还原

【Abstract】 After reviewing the basic situation,assessment method,and the corresponding result of economic loss assessment caused by consequent earthquake from several groups of swarm-type earthquake,we proposed some understanding about the assessment method and its result of economic loss assessment of consequent earthquake:( 1) Using the method of"deducting the total loss"to assess the economic loss of consequent earthquake is easier.( 2) When the magnitudes of the two earthquakes from the swarm-type earthquake are close,the economic loss of the consequent earthquake is smaller than that of the first earthquake.( 3) When we assess the economic loss of the consequent earthquake,we could appropriately raise the loss ratio in the range of loss ratio reasonable specified by the standard,which could reflect "damage gradation saturation"of some buildings and induce the increasing of real economic loss.更多还原
