encouraged that most of the independent data have a

close relationship to Equation (6) and (7) although with

some data having a little scatter.

Based on the Equation (2), (3), (6) and (7), A norma-

lized compression line considering both the effects of

initial water content and liquid limit can be obtained in

the e-log p plot written as

to evaluate the effects of soil structure quantitatively on

the intact compressive behavior for natural sedimentary

clays by enabling the initial water content being equal to

the natural water content.

4. Conclusions

The main conclusions obtained in this study are summa-

rized as follows:

(1) Oedometer tests results for three clays with differ-

ent initial water contents suggest that the compression

behavior of remolded or reconstituted clays is influenced

by both the liquid limit and initial water content.

(2) By correlating with the empirical equations pro-

posed by Burland and oedometer test data in this study, a

simple form of expressions of

are ob-

tained by the multiple liner regression, which are
