| Abstract: | The method for the conversion of any PLT results into the coefficient of subgrade reaction is put forward, which is able to take the non-linear characteristics of the p-s curves into account. The affection of settlement value chosen in the calculation of the coefficient is discussed and the relationship between the modulus obtained in laboratory tests and the coefficient is established. The said method can facilitate making good use of the data accumulated in the past. |
