混凝土防渗墙具有抗渗性能好且变形模量低、极限应变值大、适应变形力强等特点,因此在水利防渗加固工程中得到了广泛应用。文章结合惠州市惠东县尖坑水库防渗加固工程实践,介绍了混凝土防渗墙工程设计方法。 Concrete impervious wall with good impermeability and low modulus of deformation, the ultimate strain value, to adapt to strong deformation and other characteristics, so in the water seepage reinforcement project has been widely used. Combined with the practice of Jiankeng Reservoir seepage control and reinforcement project in Huidong County, this paper introduces the engineering design method of concrete cutoff wall.
