Abstract

Abstract

Through research and application in deep excavation without horizontal supports, oblique-vertical alternate piles have been popularized gradually in practice and proven effective in controlling deformation and stability of slopes. To study the mechanical characteristics of the technique, a model test and infinite element analysis by Plaxis 2D were performed. The results showed that compared with vertical piles, oblique-vertical alternate piles were more advantageous in controlling deformation and improving stability of slope. The lateral deformation of piles decreased with the increase tilt angles of oblique piles. And when the distances between piles and toes of slopes increased, the lateral deformation and bending moment of piles increased accordingly. In engineering practice, site and construction conditions should be considered to achieve more safety and economic.
