摘要
通过在室内对吹填土进行模拟加固方法的模型试验和快速结壳试验,即模拟现场吹填土沉积情况的量筒沉积试验和沉降柱试验,测定了吹填土在不同土水比及不同添加剂作用下沉降后的容重、孔隙比及含水量等物理指标。由此得出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,为进一步研究吹填土的沉积特性奠定了基础。
Indoor scale-down test and quick-crusting test were done to simulate sedimentary situation of dredger fill. Those were 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 fill.
