| 摘 要： | 在一系列室内固结试验的基础上 ,探讨了南沙软土的固结变形特性。试验结果表明 ,南沙软土的次固结效应显著 ,主、次固结的划分与固结压力有关。随着固结压力的变化 ,次固结系数表现出与当前应力状态有关的变化规律。当处于正常固结状态时 ,次固结系数近似为一常数。同时 ,固结系数和固结压力、次固结系数和压缩指数之间均有较好的相关性。

| Abstract: | Based on a series of laboratory consolidation tests, the consolidation behaviors of soft soil in Nansha are discussed.The test results show that the secondary consolidation effect of the soil is notable and the separation of primary and secondary consolidation is related to consolidation pressures.With the change of consolidation pressures, the coefficient of secondary consolidation shows a sound regularity with the variation of stress conditions.In normal consolidation state the coefficient remains approximately a constant value.There is a significant correlativity between the coefficient of consolidation and the consolidation pressure, as well as the coefficient of secondary consolidation and compression index. |
