By practice, the construction method of layer seam used to improve the layer stabilization can reduce the anti seepage criterion, simplify its construction process and bring down the investment of RCC dam to a certain degree.

实践表明,通过采用凹凸层缝施工法增强层面抗滑稳定,不仅能够在一定程度上降低坝体碾压混凝土防渗标准、简化工程施工以及降低工程造价,而且能够保证坝体的安全稳定。
