摘要
纪村土坝表层土松散,降雨后浸润线明显升高。为降低降雨对浸润线的影响,采用铲去土坝表层松散土,重新培土、夯实、固结,从而减少表层雨水的浸入,保持土坝稳定、安全。
The surface soil layer at Jicun earth dam became loose, it results in saturation line going up after rainfall. In order to reduce the impact of rainfall on saturation line, we carry out to remove the loose soil at dam surface and refill, tamp, consolidate the dam. It will prevent soil surface from rainfall immerging, which make soil dam safe and stable.
