Abstract: Besides strength parameters of soil, earth pressure is also related to stress path. For instance, when vertical stress keeps constant and lateral stress decreases to a critical stress, earth pressure is in the critical active state. The process of passive earth pressure is opposite. The active and passive failure tests of soil in triaxial test with stress path control are simulated. The relationship of stress strain of the typical stress path is discussed; and the relationship between earth pressure and lateral strain is presented. The results of test and calculation are compared. It has been found that the active earth pressure is well simulated by the proposed equation, but not for the passive pressure.

Key words: earth pressure, stress path, triaxial test, calculation method
