摘　　要：Geo-hazards,such as landslides,debris flows,dike and levee failures,ground subsidence,and sinkhole formation,result in large-scale loss of life and significant damage to infrastructure.Mitigating and preventing these hazards is a persistent challenge in geotechnical engineering.A key mechanism underlying many geo-hazards is particle migration induced by soil–fluid interactions.These interactions govern critical phenomena such as surface and internal erosion,sediment transport,suffusion,piping,slurry and grout penetration,and saturated and unsaturated soil behavior under varying conditions.For example,statistical analyses have identified internal erosion as a major factor compromising the safety of dams and dikes,being one of the primary causes of embankment dam failures.Internal erosion also affects underground structures,as it contributes to land subsidence through water piping-induced erosion,causes lateral displacements during jet grouting,induces surface settlement due to tunnel leakage,and leads to slope instability via migration of fine soil particles during rainfall.
