以先后发生过两次土质滑坡的平朔公司东露天矿边坡为研究背景,针对目前高精度岩土层界面拟合时有效数据不足和人工评价误差较大的现状,充分利用岩土层界面的地质调查点数据,有效扩充钻孔数据范围,为高精度的岩土层界面拟合提供有效数据,并利用基于Closest Point算法的结构分析模型进行Kriging插值计算,实现Kriging算法与Closest Point算法的融合,完成对露天矿边坡各岩土层的三维拟合.现场选取测量点的比对结果表明,基于Kriging与Closest Point融合算法的界面拟合,与传统的人工经验评价方法相比,能大幅提高拟合精度,且简单易行

How can the paradox with the spring be plained? In other words, which of the following statements is true 1. Equilibrium can be derived from the equiv alence of the external and the internal work 2. Equilibrium is an artifact of our imagina- tion

What do you think the eigenvectors of the element stiff- ness matrix represent? 1. a basis in which the stiffness matrix would be diago- nal (if rotated to that basis) 2. a set of nodal displacements for the element corre-

which generalizes to the statement. This reduces the number of material constants from 81 to 54. In a similar fashion we can make use of the symmetry of the strain tensor This further reduces the number of material constants to 36. To further reduce the number of material constants consider the conclusion from the first law for elastic materials, equation
