摘要:
碎屑流冲击山区建筑属多相耦合动力破坏过程,与结构的相互作用机制复杂,且受地形条件与建筑形态强烈约束。既有研究多限于单体建筑正面冲击,对地形约束下建筑群非规则布局、冲击角度变化及协同损毁机制关注不足。本文通过物理模型试验,系统研究了不同冲击角度下碎屑流对框架建筑群的动力冲击作用、协同损毁机制与动力响应规律,量化了冲击角度对碎屑流运动特性、荷载分布及破坏过程的影响。主要发现,(1)冲击角度α是调控致灾机制与破坏模式的关键参数。随α由30°增大至90°,碎屑流冲击模式从局部强冲击转为整体均匀作用,结构破坏相应由冲剪倒塌变为节点域局部损伤,建筑群整体稳定性显著增强。(2)建筑群损毁程度随α增大而递减,呈现显著的空间布局防灾韧性。α=30°时损毁最严重,前排建筑柱峰值冲击力达84.18 N,结构整体推移52 cm 后倒塌; α=90°时前排遮蔽效应显著,后排建筑基本完好,表明合理布局可有效提升群体抗冲击韧性。(3)碎屑流峰值冲击力与结构损伤程度均随α增大而递减,验证了前排建筑遮蔽效应的关键作用。(4)研究认为,优化建筑朝向以充分发挥遮蔽效能,是减轻碎屑流链式灾害、增强整体抗冲击能力的有效策略。本研究突破了传统单体建筑正面冲击的研究局限,为山区建筑群防灾选址与抗冲击韧性设计提供了试验依据与理论支撑。
Abstract:
Debris flow impact on mountain buildings represents a multiphase coupled dynamic failure process, in which the flow-structure interaction mechanisms are highly complex and strongly governed by local topographic conditions and building morphologies. Previous studies were restricted to frontal impacts on isolated buildings, with insufficient consideration of irregular building clusters under topographic constraints, variations in impact angles, and the resulting collective damage mechanisms.
