软土地基沉降速率的分析研究及其应用

本文利用Terzaghi一维固结理论推导出了在主固结阶段沉降速率与沉降、剩余沉降及固结时间的关系。结果表明，沉降速率与沉降、剩余沉降均呈线性关系，沉降速率的对数与固结时间成正比。根据这些函数关系，就可推算出最终主固结沉降、剩余沉降以及固结时间，为工程施工提供理论依据。本文还结合了工程实例，论证其可行性。

Analysis and research of settlement velocity of soft soil foundation and its application

Based on Terzaghi one-dimensional consolidation theory, this paper deduces the relationships between settlement-velocity and settlement, remnant settlement, consolidated time. The result indicates that the relationships between settlement-velocity and settlement, remnant settlement are linear, and logarithm of settlement-velocity is linearity with consolidated time. According to these relationships, the final primary consolidation settlement, remnant settlement and consolidated time can be calculated easily. An application of these relationships to a practical case is presented.
