了解疏浚土的压缩特性对于有效利用疏浚土进行排水至关重要。高初始含水量疏浚土固结参数的测定是一项费时坚韧的工作。本课题组已积累了110个一维增量荷载固结试验数据库。基于此数据库，本研究提出了一个简单的方法来确定原始压缩疏浚粘土使用三个物理参数，可以很容易地测量。疏浚土的压缩曲线可分为屈服前区和屈服后区。提出了描述这两个区域压缩行为的基本方程。相关参数与初始孔隙比和液限孔隙比相关。预测的压缩曲线与实测的积累数据库和独立的数据从文献中获得的比较。预测的孔隙比与实测值相比误差在10%以内。在工程实践中，本文的研究成果可以代替费时坚韧的试验来简单地估算疏浚土的压缩特性。
Understanding the compression behaviour of dredged clays is essential for their effective use with drainage. Measuring consolidation parameters of dredged clays at high initial water contents is a time-consuming and tough work. The research team has accumulated the database of 110 one dimensional incremental load consolidation tests for dredged clays. Based on this database, this study proposes a simple method of determining virgin compression of dredged clays using three physical parameters which can be easily measured. The compression curves of dredged clays can be divided into the pre-yield and the post-yield zones. Basic equations are suggested for describing the compression behaviour of the two zones. The associated parameters are correlated with the initial void ratio and the void ratio at liquid limit. The predicted compression curves are compared with the measured ones with the accumulated database and the independent data available from literature. The error of the void ratios predicted is found to vary within 10% compared with the measured ones. In engineering practice, the work in this study can be applied instead of the time-consuming and tough experiments to simply estimate the compression behaviour of dredged clays.
