摘　　要：基于单向固结理论,对陕西白水的低液限黏土土样进行了各向等压孔隙水压力消散试验,试验结果表明,土中孔隙水的消散参数与土的物理性质、围压和时间具有较强的关联性,试验结果可靠性强,所得到的孔压消散系数等重要参数对于工程设计和施工具有参考价值。Based on one - way consolidation theory, this paper tested the Shaanxi white - water of low liquid limit clay soilas a sample on pore water pressure dissipation. The results showed that there was a close correlation among dissipation parameterof soil pore - water, soilphysical properties, confining pressure and time. The resultwas reliability, and the important parameters such as pore pressure dis- sipation coefficient had references for engineering design and construction.
