本文在总结前人研究成果的基础上，通过模型建立、理论分析和模型试验等方法对土的固结系数及渗透系数的原位测试理论和吹填淤泥真空固结特性进行了研究。
Based on the study of predecessor, the in-situ test theories and consolidation characteristics of dredger soil under vacuum pressure were studied by theoretical analysis and model tests.
土的固结度是排水距离、固结时间和固结系数的函数。
The degree of consolidation of soils is the function of water discharging distance, duration and coefficient of consolidation.
用这种方法测定的固结系数值与原位实际的固结系数值会出现一定的偏差，主要原因是土样会不可避免地受到环境改变、运输、室内试验等一系列过程的扰动影响。
The consolidation coefficient taken by this way has disparity compared with the real value in the location. It is inescapable disturbed by such series as sampling, transporting and testing.
并对垃圾土固结过程中孔隙水及渗透系数的变化进行了分析。
Furthermore, the variation laws of the pore water pressures and the permeability coefficient during the consolidation of the refuses are analysed.
根据次固结系数双曲线模型建立的次压缩变形计算公式，既反应了软土本身性质的影响，也反应了预固结压力和再加荷压力的影响。
Based on the model, the secondary compression settlement formula is established, which reflects the influence of soft clay characteristics, pre-consolidation pressure and reloading pressure.
