Abstract: Rigid barriers are commonly used as defense measures in hilly areas to contain falling boulders and landslide debris, and the sliding displacement of these barriers is a key design consideration when space is limited. A ...

Abstract: Boulders entrained in debris flow induce high impact forces on a rigid barrier. In current design practice, the concentrated load from boulders is estimated using the Hertz equation with a load reduction factor (Kc). ...

Abstract: In this paper, a new design approach based on the principles of energy and momentum conservation is proposed for the design of free-standing rigid barriers subject to point impact. The novelty of this approach lies in the ...
