Backfilling method suitable for cracks of loess landslide

The invention discloses a backfilling method suitable for cracks of a loess landslide. The method comprises the following steps of landslide crack position and length confirming, crack segmenting, excavating, backfill compacting and vegetation restoration. The landslide crack position and length confirming comprises investigating a basic condition of the loess landslide and confirming a crack position, length and crack width needed to be processed. According to different positions and types of the cracks of the loess landslide, by taking loess in a nearby area of the loess landslide as a filling material, segmented excavating, filling, backfilling, compacting and slope surface vegetation restoration are carried out on the cracks of the landslide according to certain steps to repair the cracks of the loess landslide. A condition that rain permeates into the landslide along the cracks can be reduced greatly after backfilling, so that the stability of the landslide is improved. Meanwhile,the backfilling method h
