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。 The fractured rock mass seepage with surface infiltration is a saturated unsaturated seepage process. Aimed at the rock mass with larger crack density, the fractured rock mass is treated as continuous medium, and the mathematical model of saturated unsaturated seepage with fractured rock mass with surface infiltration is established. Using finite element method as a numerical simulation method, a finite element program of saturated unsaturated seepage considering surface infiltration was developed. An indoor model test was used to test the reliability of the program. The test results show that the model and calculation procedure are reasonable. Finally, the application of the program in a practical engineering problem is introduced.
