确定先期固结压力的试验研究

Experimental Investigation of Determining Preconsolidation Pressure

地基土的先期固结压力是判断土体应力历史的一个指标 ,在不同应力历史状况的土体变形分析也是一个重要的计算参数。因此 ,方便、准确地确定先期固结压力就显得尤为重要。在润扬大桥北锚碇科研项目中 ,对先期固结压力问题进行了试验研究 。

Preconsolidation pressure is an index of deciding the stress history of a soil layer, and is also an important computation parameter in settlement analysis dealing with soils which have different stress histories. It is very significant to determine preconsolidation pressure conveniently and precisely. Experimental investigation was proceeded for preconsolidation pressure determining in scientific research item of north concrete anchor of Ruyang bridge and preconsolidation pressure value is computed through MATLAB programme.
