摘　　要：爬模在施工过程中,整个体系受力环境极复杂,会出现施工状态及爬升状态边界条件交替改变现象从而影响预埋系统抗震性能,且施工过程中预埋系统混凝土强度、定位准确性、预埋系统与洞口冲突等因素都会影响预埋系统效能。依托七彩云南第壹城项目,运用有限元软件模拟8,8.5度抗震烈度情况,模拟计算爬模预埋件选型,根据应用情况收集整理常见问题及处理措施。During the construction of climbing formwork,the stress environment of the whole system is very complex,and the alternate change of construction state and climbing state boundary conditions will occur,which will affect the seismic performance of the embedded system. In the process of construction,the concrete strength,positioning accuracy of the embedded system,and the conflict between the embedded system and the hole are the influencing factors affecting the effectiveness of the embedded system. Relying on the First City project of Qicai Yunnan,the finite element software is used to simulate the 8,8. 5-degree seismic intensity,simulate and calculate the type selection of embedded parts of climbing formwork,and collect and sort out common problems and treatment measures according to the application.
