    Study  on  Filter  Design  of  Broadly-Graded  Soil

    More Information
    • Published Date: November 24, 1996
    • It  has  just  begun  to  study  the  mechanism  and  design  method  of  broadly  graded  soil  filter.    By  tests  in  this  paper  the  following  main  question  are  solved:①to  determine  the  equivalent  grain  size  of  critical  filter  under  the  principle  of  forming  self  filtration  layer  in  the  interface  between  filter  and  soil  to  make  soil  seepage  stability;  ②the  general  model  of  cohessionless  soil  fiter  design  is  used  in  the  filter  design  of  broadly  graded  soil,  because  the  seepage  stability  of  broadly  graded  soil  with  coefficent  of  uniformity  greater  than  100,  is  similar  with  that  of  cohessionless  soil;  ③the  appearing  propability  of  control  size  changes  with  seepage    stability  of  broadly  graded  soil,  and  it  is not  a  constant,  so  the  method  to  design  control size,  d  k=d(<2)p.70     is  presented  in  the  paper;④  the  criterion  for  filter  design  is    D    20  ≤(4~7)d  k.
