Loss is serious.There is 7.9 × 104km in the region that Chinese cumulative settling is more than 200mm2, and still have widened trend.Lead to ground
One key factor of face sedimentation is exactly stratum migration, the flowing of fine grained in soil pores in flow event, that is,
The seepage inflow erosion phenomenon that layer occurs.
In soil the seepage flow of water to soil engineering properties have a significant impact, native intensity, deformation and stablize all with water in soil
Seepage flow is related.Water seepage flow in soil can apply penetration to soil particle, and inside soil body stress state, structure, intensity is caused to occur
Change.The relative motion even overall movement of the soil body can occur when penetration is excessive, between soil particle, the loss of particle is substantially
Two processes can be divided into, be size particles separation first, followed by short grained migration.It can be basically divided into two kinds inside soil sample
Particle, one is skeleton particle substantially constant on position, its sustainable load transmits stress；Another kind is to be present in bone
Movable particle in aerial gap, position is becoming at any time, and cannot transmit stress, since structure is complicated for inside soil body, at random
Property is big, the size of hole at any time, position and become, between the mobility and skeleton particle of particle, movable particle and water
Interaction behavior be it is closely related, the infiltration water flow for flowing through hole, which always has, makes intrapore movable particle streamwise
The trend of migration, if movable grain diameter is smaller than the arrowhead being subject to, what they will be closed on from a hole inflow
Another hole, until being discharged the soil body, this generates particle seepage inflow erosion phenomenons.
And stratum occur seepage inflow erosion phenomenon it is not only related with itself basic parameter and head height of ground layer soil body, also with
The pressure in situ on stratum is related.Currently, existing research is using field test and indoor model test analog study penetration to infiltration
