重塑饱和黏性土的K0固结特性研究

以饱和重塑黏性土为对象，利用GDS三轴仪开展了不同加载速率条件下的K0固结试验，研究了土体固结过程中的应力、应变和时间的关系，并着重分析了静止侧压力系数K0的变化规律。研究结果表明:饱和黏性土的应力随时间呈直线增长，而应变与时间及应变与应力的关系曲线发展趋势与加载速率的大小有关；试验过程中静止侧压力系数有过程值，其随时间的发展也受到加载速率的影响，但在固结稳定后基本保持不变。

Study on K0 Consolidation Characteristics of Remolded Saturated Cohesive Soil

K 0 consolidation test is made on the saturated remolded soil by GDS triaxial apparatus under different loading rates to research the relationship between stress, strain and time during the consolidation of soil is studied, and emphatically analyze the variation of static lateral pressure coefficient K0. The research results show that the stress of saturated soil increases linearly with time, but the development trend of the relationship between strain and time, strain and stress is related to the loading rate; During the test, the static pressure coefficient has a process value and is also affected by the loading rate over time and then keeps constant after the consolidation and stability.
