EVALUATION FOR ENHANCEMENT OF STABILITY BY CONNECTING SEVERAL RIPRAP PARTICLES WITH WIRE

概要

In recent years, connecting ripraps has been used at some places in Japan as a material for river improvement in rapid flow, having environmental advantage of porous structure as good as individual riprap. This material is made by connecting riprap using wires, and set on riverbed. As the wire connectors preserve stability more than using usual riprap individually, they are expected to save labor for river maintenance work and costs. Although such materials are in practical use in river channels, they have not been subjected to hydraulic analysis. We verified the effect of enhancement for limit of breakaway by experiment and theoretical estimation of its shear stress using stochastic model.
