| 摘 要： | 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中它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。依据理论研究和试验分析，提出了一种新的确定方法：数学模型法。润扬大桥土样试验的结果证明了此法的可行性。 |

| Abstract: | Preconsolidation Pressure is an index of deciding the stress history of a soil layer; and it is also an important computation parameter in settlement analysis dealing with soils which have different stress histories. It is very significant to determinepreconsolidation pressure conveniently and precisely. A new method of determining preconsolidation pressure named asmathematical model method based on theoretical research and test analysis. Results of tests for soil samples taking from Runyang great bridge demonstrated that the application of the method is recommendable. |
| Keywords: | preconsolidation pressure methods of determining preconsolidation pressure mathematical model method point ofmaximum curvature model applicability |
