摘要
通过在室内对吹填淤泥进行模拟试验,测定了吹填淤泥沉降后的容重、孔隙比及含水量等物理指标的变化过程,证明了吹填泥浆在静水中的沉降过程可以划分为两个阶段,即细颗粒絮凝下沉为主的沉积阶段和泥浆自重固结阶段.通过对其力学指标进行的初步研究,证明吹填淤泥在经过一定时间的固结后具有了一定的承载力,可以用加固饱和软粘土地基的方法对吹填区域进行加固.
Indoor scale-down test and quick-crusting test were done to simulate sedimentation situation of dredger fil1,known as dosimeter-sediment test and sediment column test.Unit weight,void ratio and water content under different soil-water ratios and different additives of dredger fill have been determined.According to these data,subsidence of dredger fill-grout in standing water can be divided into two stages： fine-particle flocculation stage and mud self-weight consolidation stage,which laid foundation for further study on characteristics of sedimentation of dredger fil1.
