摘　　要：云南以礼河四级电站复建工程出线竖井为圆形断面,开挖后直径10.3m,竖井长度约280m,混凝土衬砌采用滑模进行施工。由于竖井长度较长,如何保证滑模施工过程中竖井偏差满足规范要求,以及出现偏差后采取何种纠偏方式是关键点。从事前控制、事中控制、事后控制3个方面系统地总结了滑模施工过程。The outgoing shaft of Yilihe Fourth Cascade Hydropower Station Reconstruction Project is a circular section with a diameter of 10.3M and a length of 280m after excavation.Concrete lining is constructed with sliding form.Due to the long shaft length,how to ensure that the shaft deviation meets the specifications during sliding form construction and how to correct the deviation after the deviation occurs are the key points.This paper systematically summarizes the construction process of sliding mode from three aspects:pre-control,in-process control and post-control.

关 键 词：出线竖井 滑模 纠偏
