摘要
分析了天津地区吹填土的基本工程特性,得到了粒度成分、物理化学性质、矿物成分等性质。然后利用不同水头作为堆积荷载,在自制的荷载沉降仪模拟装置中观测在不同水头荷载下,吹填土的沉降量、孔隙水压力、渗流量与时间的关系,绘出曲线进行时效性分析。同时着重对土的沉降特性包括固结度、沉降速率进行定量分析,评价吹填土的固结情况。
The dredger filling form the Tianjin area of capital projects is analyzed and tested in this paper, including the ingredients are characteristics of physical and chemical properties and basic indicators of the physical nature of some of the results. Secondly the timeliness of pore water pressure, settlement and seepage discharge of the dredger filling is observed in different head water in the self-made load settlement simulator, meanwhile draw the carve to analyze the timeliness. At the same time this paper emphasized on the settlement characteristics of the soil including degree of consolidation and settlement rate to make quantitative analyzed, evaluated the consolidation of the dredger filling.
