摘　　要：白市电站大坝监测系统已经运行7年,通过监测资料分析廊道渗漏规律及成因,分析表明,大坝坝段间接缝开合度与库水温的变化密切相关,即气温降低而增大,气温升高而减小,廊道渗漏量大小与库水温呈正相关性。整个大坝廊道渗水量的周期变化是安全的,但要预防低温天气带来的负面影响。The monitoring system of Baishi hydroelectric dam has been in operation for 5 years.The permeate capacity of the corridor is measured by the automatic measurement system and the reliability and correctness of the data are checked.It is showed that the data correctly reflect the change of the corridor permeate capacity.The alteration of structural joints and the construction joints of the dam was closely related to the alteration of water temperature.The permeate capacity of the corridor and the water temperature of reservoir were in close relationship.
