摘要
除险加固工程中常用防渗帷幕作为降低坝体浸润线的措施,然而施工质量不达标、控制难度大等因素可能会导致防渗墙内部出现裂缝问题,削弱防渗效果。对此,结合现场观测结果,利用透明土进行试验,对不同缺陷位置和形式下的防渗墙防渗效果进行研究,并对注浆效果展开分析评估,可以为工程加固提供指导。
In risk control and reinforcement projects,seepage control curtains are commonly used to lower the phreatic line within the dam body.However,factors such as substandard construction quality and high control difficulty may lead to cracks within the seepage control wall,compromising its effectiveness.To address this issue,experiments using transparent soil were conducted in combination with field observations to study the seepage control performance of walls with different defect locations and forms.Additionally,an analysis and evaluation of grouting effectiveness were carried out to provide guidance for dam reinforcement projects.
