General stress-strain-time function for soils
Stress-strain-time behavior of soils may assume variety of forms, depending on such factors as soil type, soil structure, stress history, drainage conditions, and type of loading; test results show that there exist linear relationships between logarithm of strain rate and logarithm of time for given stress and between logarithm of strain rate and stress at any given time, provided creep stress level is between practical limits of about 30 to 90% of initial soil strength; these findings lead to simple three-parameter general stress-strain-rate-time relationship; integration of this relationship yields creep curves which are observed to agree in form with experimental results.
