摘要：

通过对试验实测资料的分析,讨论了孔隙水压力仪埋设位置,固结系数取值,应变固结度与应力固结度的差别和欠固结四种因素对固结度计算结果的影响,提出在软基加固处理固结度计算分析时,应考虑这些影响因素。

Based on the analyses of the measured data,the influence of four factors on the calculated result of degree of consolidation is discussed,namely the positions where the pore water pressure gauges were placed,the values of coefficient of consolidation,the difference between the degree of consolidation under strain and the degree of consolidation under stress,and the under-consolidation.It is pointed out that these affecting factors should be given due consideration when the degree of consolidation is calculated and analyzed for soft soil improvement.
