摘要
有地表入渗的裂隙岩体渗流是一饱和非饱和渗流过程。针对裂隙密度较大的岩体 ,把裂隙岩体等效为连续介质来处理 ,建立了有地表入渗的裂隙岩体饱和非饱和渗流数学模型。采用有限元方法作为数值模拟手段 ,编制了考虑地表入渗的饱和非饱和渗流有限元计算程序。用一室内模型试验对程序的可靠性进行了检验 ,检验结果表明模型和计算程序是合理的。最后介绍了程序在一实际工程问题中的应用。
Water flow in fractured rockmass due to surface infiltration is a saturated unsaturated seepage process. In the light of high density fractured rockmass, which can be equivalent to continuum, a mathematical model for saturated unsaturated seepage in fractured rockmass due to surface infiltration is established. Finite element method is used as numerical simulation means and a program used to calculate saturated unsaturated seepage due to surface infiltration is worked out. A model experiment is used to examine the reliability of the program. The result shows that the model and the program are reasonable. Finally, the application of the program in a practical engineering problem is presented.
