<b>Effect of weakening lateral confinement on shear behavior in granular material</b>

Landslides and rock avalanches involve masses of soil and rock that laterally spread as they flow downhill, influenced by changes (the weakening of lateral terrain constraints) in the surrounding terrain.滑坡（Landslides）与岩崩（rock avalanches）指沿坡向下流动过程中发生侧向扩展的土体与岩体团块，其形成受周边地形变化（即侧向地形约束的弱化）的影响。
