摘要
严寒地区冬季温度骤降很容易使大坝形成裂缝,甚至是贯穿性的裂缝。针对这种温度裂缝,采用柔性处理的方法,既满足裂缝在伸缩过程中的变形,又起到了防渗作用。该方法具有十分明显的止水效果,技术可靠、投资少,降低了水库大坝维护管理费用,有较好的经济效益。
The sudden drawdown of temperature in winter can easily cause cracks,even the cross-cutting cracks for the dam in the severe cold area.According to the temperature crack,the flexible treatment method is adopted,which could meet the crack deformation in the stretching process and play an important role in the seepage.Owing to the obvious sealing effect,reliable technology,less investment and lower the maintenance charge of the dam,the method has better economic benefits.
