中文摘要：
以辽宁大连瓦房店输水工程饱和流塑淤泥层地段管道施工难题作为分析对象,选取关键地段代表性土样开展试验研究,研究饱和流塑淤泥的次固结特性,并将变形与孔压消散规律的实验结果和太沙基固结理论计算结果进行对比。结果表明：饱和流塑淤泥的次固结系数与固结压力无关,相同固结压力作用下经过预压的淤泥的次固结系数比没有经过预压的淤泥的次固结系数大大减小。
英文摘要：
Taking the pipeline construction in the saturated flowing muck reach of Wafangdian water supply project in Dalian of Liaoning Province as the analysis object,the representative soil sample is selected to make the experimental research on the secondary consolidation characteristics of saturated flowing muck,and the experimental results of deformation property and pore pressure are compared with the calculation results of Karl Terzaghi consolidation theory.The results show that the secondary consolidation coefficient of saturated flowing muck has no relation to the consolidation pressure,and the secondary consolidation coefficient of the silt soil under same consolidation pressure after preloading is much smaller than that without preloading.
