疏浚粘土固结不排水应力-应变归一化特性分析

将疏浚粘土应力一应变关系与粘性土的含水率联系起来，对于实际工程而言具有很大的参考价值。传统重塑土应力一应变归一化特性的研究只是针对某一特定性质的土体而言，这种归一化的研究方法显然具有一定的局限性。采用归一化含水率w／wl作为归一化因子，对主应力差渐进值进行归一化．探讨了双对数坐标系下主应力差渐进值与w／wl的线性关系。在此基础上基于Konder提出的双曲线模型将主应力差渐进值作为归一化因子，对三种不同疏浚粘土的应力一应变特性进行归一化分析，通过与实验资料的对比表明，提出的方法具有很好的归一化效果。

Normalized Stress-Strain Behavior of Dredged Clayey Soils in Triaxial Undrained Shear Test

It does a great reference value to link the stress-strain relationship of Dredged Clayey Soils with water content for actualprojects. Traditional researches on normalized stress-strain behavior of remolded soils is just for a specific kind of soils concerned, which obviously has some limitation.The normalized factor w/wL is introduced to normalize the ultimate value of principle stress difference, which refer to the linear relationships between the ultimate value of principle stress difference and w/wL in double logarithmic coordinates. On this basis, the research on normalized stress-strain behavior on three different kinds of Dredged Clayey Soils, which is based on the hyperbolic model proposed by Konder and aqopted the ultimate value of principle stress difference as the standard normalized factor. It shows a good normalized results by comparing with the experimental results.
