【摘要】 依据Terzaghi固结理论解对固结试验结果进行了反演分析。分析发现,固结过程中固结系数Cv是变化的,变化范围可达3个数量级,大大超过了传统认识的预期。试验结果表明,固结系数并不是Terzaghi假定的固定参数,而是按加载周期循环重复,固结过程中持续变化的过程因子。更多还原

【Abstract】 Terzaghi consolidation theory assumes that the consolidation coefficient is constant. Laboratory observations of the consolidation behavior exhibit discrepancies between the theory and the results. Based on Terzaghi consolidation solusion the back analysis of consolidation coefficient is conducted. The results show that the consolidation coefficient keeps changing in the process of the consolidation, ranging up to 3 orders of magnitude. The consolidation coefficient is not a fixed parameter but a process factor which repeats in each load and constantly changes in the process of consolidation.更多还原
