Abstract With the widespread application of the new slope reinforcement method using soilbags，the drawbacks of extensive layout of soilbags have been gradually revealed. Therefore，it is imperative to research on the optimized application of soilbags. The pressure failure tests in seven cases changing the parameters of soilbags，including the size and form were carried out through the laboratory physical scale model test. In order to explore the reinforcement effect and its law of the width and tail length of soilbags on soil slope，the failure mode and failure pressure of each slope specimen，the vertical distribution law and horizontal transfer rule of earth pressure and the change trend of earth pressure with increasing load have been analyzed. The experimental results indicate that soilbags are effective in reinforcing soil slopes. The larger the reinforcement width of the soilbag is，the better the effect is. However，the longer tail length is not better in the case that the economic cost is constant.

Key words： slope engineering soil slope soilbags earth pressure model test
