摘要:
针对土体的非线性固结特性和实际工程中存在的变孔压排水边界,在土体一维非线性固结理论的基础上,提出严格满足初始条件的变孔压排水边界条件,建立了考虑变孔压排水边界条件的一维非线性固结模型,并给出了相应的解析解。在验证解析解正确性的基础上,探讨了按变形定义固结度Us和按孔隙水压力定义固结度Up之间的差异,总结了土的非线性特性和边界条件等因素对土体固结过程的影响规律。
Abstract:
According to the nonlinear consolidation characteristic and the existence of unsteady pore pressure boundary,boundary conditions were raised based on soil 1-D non-linear consolidation theory to strictly meet the primary conditions. A new model was then established and the solution based on the conditions were given. Furthermore,the solution was verified and the differences between Us and Up which were the consolidations defined respectively in terms of settlement and pore pressure,were discussed. Finally,the influence of nonlinear consolidation and boundary conditions on consolidation process was summarized.
