There are many fine and small particles in the siltwater.In the seepage process of the reservoir,the silts will be sediment,infileration to form a sediment doposition with small permeable in the bottom of the reservoir: Also when the silt water was enfiltrated into bottem of reservoir,it can play the functions of filling,squeezing and pressing,percolate consolidation and improving to inerease the density of the sediment deposition and reduce the seepage.Through the real case investigation for the seepage pr...
