Method and structure for filling reservoir roadbed with silty mudstone filler

The invention discloses a method and a structure for filling a reservoir roadbed with silty mudstone filler, the structure comprises a fill body with unweathered silty mudstone as main filler, a first inverted filter and a second inverted filter are laid on the outer side of the slope of the fill body, the first inverted filter is located on the outer side of the second inverted filter, and the second inverted filter is located on the outer side of the first inverted filter. A water facing side dry rubble slope protection layer is arranged on the outer wall of the first inverted filter layer, and a filling slope toe protection wall is arranged at the slope bottom; the silty mudstone serves as the filler, good economical efficiency is achieved, collapse and sliding of the immersed slope can be effectively avoided, piping damage of the slope can be effectively prevented, and the beneficial effects of being high in construction speed, high in safety and high in practicability are achieved. 本发明公开了一种粉砂质泥岩填料填筑水库路基的
