摘要
研究了软土固结系数在压缩过程中随应力水平变化的规律,推导出正常固结和超固结状态下固结系数与固结应力之间的表达式,通过室内渗压试验进一步探讨和验证固结系数这一特点。该结果为数值分析的准确性提供了保证。
The relationship between coefficient of consolidation and effective stresses of a soft clay is researched. An expression between them is derived. A series of laboratory tests are also conducted to prove its validity. The positive results can increase the accuracy for the numerical analysis of consolidation.
