Seismic Stability Analysis of Pre-stressed Rope of Anti-slide Retaining Wall

摘要

In this paper, the new combined anti-slide structure of pre-stressed rope anti-slide retaining wall was presented, which can be taken the combination of advantages of the both rope and retaining wall, aiming at the efficient, economical and fast treating landslide. Based on the kinematical approach of upper bound theorem, the collapse mechanism is investigated by the wall-rope-soil system. The yield acceleration factor and the corresponding inclination of failure surfaces can be estimated once the seismic acceleration threshold for slide is exceeded. The obtained results show that enhancing the pre-stressed rope force can effectively improve critical yield acceleration factor.
