Zhejiang Datang Wushashan power plant is composed of farmland and aquaculture ponds in the Xizhou seawall, which are backfilled with artificial riprap. In order to block the seepage path in the rock fill layer, the vertical curtain cement paste grouting anti-seepage reinforcement measures are adopted to block the connection between the underground water and the surrounding surface water in the plant area, so as to achieve the purpose of gas closure. This paper mainly analyzes and evaluates the technical indexes, such as grout diffusion range and impermeability, of the cement paste grouting curtain, via field tests and two dimensional numerical simulation based on the platform of PFC2D or Geostudio.
