Abstract: The purpose of this study is to investigate the stability and failure mechanism of embankments on sloping ground with weak interlayer. Centrifugal model tests and numerical simulations are conducted; and some useful conclusions are drawn as follows. The failure mechanism of embankments on homogeneous sloping ground is still circular sliding. Due to the effect of weak interlayer, the tensile crack will emerge and develop easily; and the embankment will become more instable and slide along the weak interlayer.

Key words: weak interlayer, embankment slope, stability, centrifugal model test, numerical simulation
