淤泥固结过程中的释水规律及其室内测定方法研究

An approach on pore water release of ooze consolidation

从土体压缩释水的角度考虑固结 ,认为淤泥类软土的固结是由于在外力作用下土体内所含部分自由水的被迫释放排出 ,土体积减小所致 ,即土体是释水固结而非渗透固结 ,土体固结存在释水函数。用释水函数取代太沙基固结模型中的渗透系数 。

In order to study the inherent behaviors of ooze consolidation, some corrections were made on the basic hypotheses of the Terzaghi's consolidation theory. By considering the compaction drainage, it is held that the consolidation of ooze is caused by the withdrawing of gravitational water from the soil and the reduction of pore water volume under the action of external force. So the nature of ooze consolidation is pore water release but not seepage.
