摘　　要：为了对现存碉楼的现状进行合理评估,基于易损性构建了一套碉楼震后可保护性评估方法,以黑虎寨碉楼、丹巴碉楼和直波碉楼为参考,建立了不同外形、不同高度、不同墙体收分率的碉楼有限元模型,基于耐震时程地震分析进行了易损性与可保护性的评估,探明了现存碉楼的可保护情况。In order to conduct a reasonable assessment of the current status of existing watchtowers,a set of post earthquake protectability evaluation methods for watchtowers was constructed based on their vulnerability.Using the Heihuzhai watchtower,Danba watchtower,and Zhibo watchtower as references,finite element models of watchtowers with different shapes,heights,and wall shrinkage rates were established.Based on seismic time history analysis,the vulnerability and protectability of the watchtowers were evaluated,and the protectability of the existing watchtowers was explored.

关 键 词：藏式碉楼 易损性分析 可保护性分析 耐震时程
