Filter test
Filter test
(OP)
Hi,
I want to perform a filter-test without base material and just with suspension. I want to define a function of resistence against erosion. I need to know which parameters of Soil(Filter and Suspension) and Water is important for this test. Which parameters must be measured before and after this test.
For example I thought that temperature have to be constent during the tests, measuring Q and pressure are essential and I have to perform specific gravity test, Grain size distribution, ....
I appreciate helpful tips on literature and web sites, specialy about tests with suspensions and Kontakt erosion and suffossion.
Thanks

RE: Filter test
Is this a filter for a dam? If so, avoid "reinventing the wheel." There are two papers by Sherard, Dunnigan, and Talbot in the June 1984 ASCE Jnl of Geotechnical Engrg. They will get you to a safe, workable filter design. The same thing appears in the USBR filter design manual if you get a copy from the 1980s or later.
RE: Filter test
Therefore it is necessary to test the soil of dike. those tries, which was accomplished by sherard or the others, are with 2 layers, a base and a filter layer. I want to perform this Test only with a layer and feed base materials as suspension into filter materials.

Sherard, J.L. (1979), "Sinkholes in Dams of Coarse, Broadly Graded Soils," Thirteenth Congress on Large Dams, Question 49,R,2, New Delhi.
I am not clear on what configuration you have in mind for your test. There is probably not an ASTM or BS standard for it.

RE: Filter test
as mentioned above I want to perform a filter test not with filter/base combination but just with suspension. (cvg)
