Abstract:

Characters of lateral displacement, vertical settlement and stability of embankment on inclined weak foundation with stage construction have been studied with FEM. It is shown that the lateral displacement of inclined weak foundation distributed inclined and got its maximal value at the lower toe of embankment, which are different from that of horizontal weak foundation distinctly. The stability of embankment on inclined weak foundation is greatly less than that of horizontal weak foundation, which maybe destructed along the inclined surface of inclined weak foundation. The results also show that anti-slide piles is an effective reinforcement of inclined weak foundation, which reduced the value and increment of lateral displacement of embankment, impeded the failure of embankment along the inclined surface of inclined weak foundation, and enhanced the stability of embankment effectively.

Key words: inclined weak foundation, embankment, finite element method, anti-slide piles, deformation behavior
