摘　　要：坝基透水边界对坝体渗流特性具有重要影响。针对坝基的非线性固结特性及实际工程中存在的广义透水边界,提出了符合非线性一维固结特征的广义透水边界条件,建立了广义透水边界下的非线性一维固结理论模型,并给出了相应的解析解。通过公式的退化,导出了一系列经典解答。在解答正确性得到验证的基础上,通过算例分析了坝基非线性参数和广义透水边界条件等因素对土体固结特性的影响。The permeable boundary of dam foundation has an important influence on the seepage characteristics of the dam.According to the non-linear consolidation properties and the existence of generalized drainage boundary in the practical engineering,boundary conditions w ee put forword based on 1D non-linear consolidation theory to meet the consolidation characteristic.A new model was established by using generalized drainage boundary conditions and the solutions were given based on the conditions.Furthervnore,by the degeneration of the parameters,a series of solutions were derived.Finally,based on the validation of the solutions,the influence of non-linear consolidation characters and boundary conditions were summarized.
