摘　　要：在常规主固结度计算中假设渗透系数保持不变,导致计算结果与实际情况有较大偏差。为增加主固结度计算精度,文中假设土体渗透系数在固结过程中以双曲线规律减小,对常规主固结度计算方法进行改进。通过实例对比分析,改进方法计算结果与实际更为贴近,说明改进方法是可行的。Assuming that soil permeability coefficient is constant in the conventional primary consolidation calculation,it has great difference between the conventional consolidation calculation and actual situation.To increase the calculation accuracy,the conventional method of consolidation is improved through the way of assuming that soil permeability coefficient decreases with the hyperbolic law during the primary consolidation process in this paper.It shows that the calculation results of the improved method are closer to the actual situation through the comparison in the actual project,indicating that the improved method is feasible.
