A formula of active earth pressure on retaining wall was proposed which considers the cohesion force on sliding plane and the adhesive force on interface of soil and retaining wall.
考虑滑裂面上填土的粘聚力及填土与墙背接触面上的粘着力，推得了粘性填土挡墙上的主动土压力计算公式。

The effect of unloading confining pressure on cohesion is more obvious than that of angle of internal friction.
卸荷对黏聚力的影响比对内摩擦角的影响大。
3
The friction factor obtained from the regression analyses of the peak strength, residual strength and confining pressure are roughly equal and the cohesion is reduced by 54.4%.
