Abstract

It is proposed that PLT curve is fitted by hyperbola in this paper.On the curve,it is easy to establish the failure standard ,then the coefficient of subgrade and the internal relation can be obtained,and an empirical formula,which estimates the secant coefficient of subgrade from ultimate bearing capacity or CPT parameter,is suggested
- PLT,
- ultimate bearing capacity,
- coefficient of subgrade
