首先根據邊坡空間信息系統和邊坡的「多層dem 」模型的原理,研究了小浪底東苗家滑坡體多層dem模型的建立,以及物理力學參數分佈的數字模型描述。 -
A digital elevation model ( dem ) is a digital file consisting of terrain elevations for ground positions at regularly spaced horizontal intervals. dem may be used in the generation of three - dimensional graphics displaying terrain slope, aspect ( direction of slope ), and terrain profiles between selected points
數字高程模型( dem )是反映高程信息的數字地面模型,它是以數字的形式按一定的結構組織在一起、表示實際地形高低起伏和地形大小特徵的空間分佈模型。 -
By the method used in 13, 32, one can estimate the mean depth d and the effective length l in each grid. the slope of the aquifer can also be calculated through an analysis of the digital elevation model. the two parameters a and b in the quasi - steady subsurface model can be calculated by the following method : the nonlinearity parameter b is taken to be 2. 0, the parameter a can be calculated by plotting the values for dq dt versus q in a log - log graph 13
