摘要
非饱和土广义固结问题所具有的内含远比饱和土固结问题丰富、复杂。本文用守恒型差分格式离散和求解非饱和土一维广义团结非线性方程组。通过3个算例分析,论证了所建立的非饱和土一维广义固结数学模型,不但能正确揭示非饱和土一维广义固结的过程,又可求解饱和土固结、非饱和土渗流等特殊问题。
This paper presents a mathematical model for one-dimensional generalized consolidation of unsaturated soils. In the model, the coupling effects between water and air flow and soil skeleton deformation are considered. A finite difference method has been used for the numerical solution of the mathematical model developed. Some case histories are solved numerically to demonstrate that the model not only can reveal the actual procedure of the generalized consolidation of unsaturated soils, but also can simulate some particular problems, such as the saturated consolidation and the unsaturated seepage flow.
