| Abstract: | Coefficient of the lateral pressure'at rest' is an important parameter in the calculation of geotechnical mechanics.Based on the deformation formula of Loading Test in site,the coefficient of lateral pressure'at rest' for normally consolidated soil is developed.The results are consistent with the empirical results.Combined with the formula proposed in this paper,the coefficient of lateral pressure'at rest' for over-consolidated soil is discussed.It is reasonable in theory and realizable in practice. |

| Keywords: | coefficient of lateral pressure 'at rest' normally consolidated soil overconsolidated soil overconsolidation ratio |
