摘要
通过对三峡工程二期土石围堰 1998年汛期以来的安全监测资料分析 ,阐述了围堰的变形特征及其影响因素、防渗墙的防渗效果及其应力应变变化规律等 ,认为目前围堰整体工程性态正常 。
The safety monitoring information to the 2nd stage earth rock cofferdam since the flood season of 1998 are emphatically analysed.The deformation features of the cofferdam and their affect factors,impermeable effects of anti seepage walls and reqularities of variation of their stress strain are represented.It is concluded from the analysis that the cofferdam is wholly in good working order now,but late safety monitoring work must be continued and strengthened.
