摘　　要：土是弹塑性变形体,先期固结压力使土塑性变形减小,土的弹性变形与土类及压力有关,与土的先期固结压力无关。根据土弹性、塑性变形与先期压力之间的变化规律,可以找出一个土的先期固结压力的测定方法。Earth is deformation of elastic-plastic. The previous consolidation pressure makes the transformation of earth plasticity reduce. The elastic deformation of earth is related to earth kinds and pressure, not related to its prophase. According to the changing rules between earth elasticity and earth plasticity and previous pressure, we may find out a measurement method for previous consolidation pressure.

关 键 词：弹塑性 压缩量 先期固结压力
