摘　　要：通过对紫坪铺2号泄洪排沙洞震损修复工程固结灌浆过程中的抬动监测,介绍抬动观测点的布置、抬动监测装置的安装以及抬动监测过程控制,分析影响抬动变形的因素及灌浆抬动影响范围随距离增大而减小的特点,指出本次抬动监测存在的问题。Based on the lifting monitoring of consolidation grouting process of the rehabilitation project of No.2 flood discharge and sediment diversion hole of Zipingpu Hydropower Station due to earthquake damage,the layout of lifting observation points,installation of lifting monitoring devices and process control of lifting monitoring were introduced.The factors for the lifting deformation and the characteristics of the affected area of lifting caused by consolidation grouting,which decreased with the increase of the distance,were analyzed.The existing problems in the lifting monitoring devices were put forward.
