摘　　要：某大型输水渠道某段遭遇高强度降雨,疑似下部换填土体滑移,造成渠道过水断面衬砌板隆起破坏。结合现场出现问题分析了破坏原因,对险情渠段进行完建期、正常运行期及遇险后的边坡稳定进行系统分析,提出了控制渠段地下水位,加强坡体排水能力,增强换填土体强度等应急抢险处理措施,对以后大型输水渠道应急抢险有一定指导意义。A sections of a large water delivery channel encountered a heavy rainstorm.It was suspected that the underfill soil slipped,resulting in heave and damage of the lining plate of the passage section of the channel.Combined with the field problems,the failure reasons are analyzed.Systematic analysis was made on the slope stability during the completion period,normal operation period and after the distress of the dangerous channel section.It is proposed to control the underground water level and strengthen the drainage capacity of the slope.Some emergency measures are put forward,such as controlling the underground water level,strengthening the drainage capacity of the slope and strengthening the strength of the reclaimed soil.It has certain guiding significance for the emergency rescue of large water conveyance channel in the future.
