中文摘要：

为分析制样含水量对重塑软黏土的力学特性影响,用单向固结仪和三轴仪分别对不同泥浆含水量固结而成的重塑样开展了单向压缩试验和固结不排水剪切三轴试验。试验结果表明,重塑样的初始孔隙比随制样含水量的增大而增大,从而引起压缩曲线的上移以及压缩指数的增大,土体的抗剪强度减小,孔隙水压力增大;但初始含水量对土体的有效应力比和临界状态影响不大;制样含水量对重塑样力学特性的影响的界限含水量约为2.0倍液限含水量。最后,用孔隙指数对试验结果归一化,得到不同初始孔隙比重塑样的压缩曲线和剪切强度可基本归一化为土的固有压缩曲线和固有强度曲线。

英文摘要：

A series of odometer and consolidation-undrained triaxial tests have been carried out on the reconstituted samples,which were consolidated into samples with different initial slurry moisture content,are employed to study the effect of initial water content on the mechanical behavior of reconstituted clay.The test results show that the initial void ratio of reconstituted samples will be increased with the increasing slurry water content and the largest void ratio sample will have highest location of compression curve and its compressibility;the shear strength decreased with the increasing of slurry water content and the change rule of pore water pressure is the opposite.However,the effective stress ratio and critical state line affected by the slurry water content was not obvious overall,and the above conclusions were only suitable for the change of slurry water content within 2.0 times the liquid limit water content of soil,which was determined as the limits of slurry water content in this study.Lastly,the compression curves and undrained shear strength,using the void index,can be normalized to the intrinsic compression line and intrinsic strength line well respectively.
