The Three-Dimension Saturated-Unsaturated Seepage Analysis Under Atomized Rain Of Hydropower Project With High Slope
Abstract Based on the background of Goupitan Hydropower Project high slope to research saturated-unsaturated seepage problems under atomized rain. Firstly, influence factor of flood discharge atomization is analyzed, the rainfall intensity and distribution of flood discharge atomization is researched by fuzzy mathematics, using the measured data, and a membership function of flood discharge atomization is built on the basis of statistical analysis and expertise, and then forecast the rainfall intensity and range by the fuzzy comprehensive judge. Secondly, According to the control equation of saturated-unsaturated state, the integral saturated-unsaturated unsteady seepage control equation is constituted on the connection of saturation degree. The FEM computation format of mathematic model is deduced by Galerkin weighing margin method, the compute iterate mode of nonlinear FEM is developed, and the three dimensional FEM program of computing saturated-unsaturated unsteady seepage under ground seepage condition by FORTRAN language, the solving technical methods and convergence speed are improved. At last, based on the slope geological characteristics, the slope geological model and calculation model are building, the saturated-unsaturated seepage field under ground seepage condition for the high rocky slope is simulated, and the result could provide important scientific references for seepage control measures and safety estimate in Hydropower Project.
