The use of steel flexible barriers to mitigate landslide risk on natural hillsides is becoming
common in the past decade in Hong Kong. The current design approach for this kind of …

ABSTRACT A new type of flexible debris-resisting barrier has been designed using the state-
of-the-art analytical force approach for mitigation of channelised debris flow hazards in a …

Modelling flow-like landslides interacting with barriers poses significant challenges,
particularly to predict the impact dynamics. For the design, it is essential to assess the forces …

Flexible barriers trap large particles and boulders in debris flow but allow slurry and small
particles to pass through. Field tests and real cases indicate that a certain amount of slurry …

Abstract In Hong Kong, design practice adopts the hydrodynamic load model to estimate the
dynamic soil debris impact load on reinforced concrete debris-resisting barriers. A dynamic …

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 …

A channelized debris flow is usually represented by a mixture of solid particles of various
sizes and water flowing along a laterally confined inclined channel-shaped region to an …

The dynamics of debris flows are fundamentally governed by the interaction between the
solid and fluid phases. However, current approaches used to estimate impact load treat …

A new analytical model is proposed to estimate the peak impact pressure of debris flow
exerted on a rigid barrier. The new model consists of two terms, p= α 1 ρ 0 gh 0+ 0· 5 ρ 0 u …

Effective design of mitigation measures against debris flow hazards remains a challenging
geotechnical problem. At present, a pseudo-static approach is commonly used for the …
