摘要
通过比较天然软黏土原状样一维压缩曲线与基于重塑土一维压缩曲线确定的定量变化规律,建立了天然软黏土屈服后压缩曲线的定量预测方法,给出了与重塑土一致的压缩参数定量表达式,通过搜集已有文献中41个天然原状土样一维压缩试验数据,验证了定量公式的有效性和适用范围,并说明天然软黏土屈服后的压缩性状与土结构性无关。
Through comparing the quantitative law of natural soft clay sample-compaction curve and compaction curve based on remolding,it establishes quantitative prediction method of natural soft clay compaction curve,shows the quantitative expression formula of remolding soil compaction parameter.Through collection 41 natural original soil sample-compaction test data in existing literature,it testifies the effectiveness and application scope of quantitative formula,and illustrates the compaction of natural soft clay compaction is not related to soil structure.
