ABSTRACT
Best Value for x for Coarse Grained Soils From laboratory tests determine k for various void ratios e of the sample. Then plot curves k versus 2e2(l+x) /(1 +e) for values of x = 0, 0.25, 0.5 and k versus e2• The plot that fits well gives the best value of x. It has been found from experimental results that the function
gives better agreement than the other functions. However, the function F4(e) = e2 is sometimes preferred because of its simplicity and its fair degree of agreement with the experimental data. Fig. 4.12 present experimental data in the form of k versus functions of e.
