现有电渗固结理论和数值模型通常基于饱和土假设,与实际情况有差距。基于分段线性差分法,建立一种考虑饱和度变化的一维电渗固结模型UEC1。该模型考虑了土体电渗固结过程中饱和度的变化及土性参数的非线性关系,并编制了FORTRAN计算程序。UEC1在考虑饱和度变化情况下的计算结果与实测结果吻合。结合算例,给出了考虑饱和度变化情况下的电渗固结数值解,分析了固结过程中孔隙水压、孔隙气压、饱和度及沉降量随时间的变化规律,其中残余饱和度对土体电渗固结沉降量的影响显著。 The existing theories and numerical models of electroosmosis consolidation are usually based on the assumption of saturated soil, which is far from the actual situation. Based on the piecewise linear difference method, a one - dimensional model of electroosmotic consolidation UEC1 considering saturation change was established. The model takes into account the change of saturation and the nonlinear relationship of soil parameters in the process of soil infiltration consolidation, and compiles the FORTRAN calculation program. The calculation results of UEC1 under the condition of considering the saturation change coincide with the measured results. The numerical solution of the electroosmosis consolidation considering the change of saturation is given. The variation law of pore water pressure, pore pressure, saturation and settlement with the time is analyzed. The residual saturation The effect of soil electroosmosis consolidation settlements is significant.
