Abstract

Abstract

Root piles and chemical grouting are the combination of two reinforcing slope methods. Root piles offer anti_slide and anchor function for slope, and chemical grouting can improve soil shear strength efficiently. If the traditional limit balance is used to analyze the slope stabilized by root piles and chemical grouting, the evaluation result will not be accurate. According to the mechanism of root piles and chemical grouting to reinforce a slope, and the shear strength parameters of the composite of grouting and soil obtained by field test, a slope is simulated to analyze stability by strength reduction of FEM. The results show that strength reduction of FEM can not only reflect the mechanism of root piles and chemical grouting but also obtain safety factor and glide surface, hence adopting root piles and chemical grouting to reinforce and rehabilitate a slope is feasible.
