WANG Zhi-liang, YU Feng, YIN Zong-ze. Study on calculation of consolidation problem using nonlinear local point interpolation method[J]. 2004, 25(2).DOI:
Local point interpolation method is a new type meshless method. Because its shape functions for displacements and pore water pressures possess delta function property
the essential boundary conditions can be imposed easily. After the basic theory is introduced and the main equations for solving Biot’s consolidation problem are developed
the consolidation and settlement of one multi-layer soft ground subjected to heaped loadings are calculated with it. Furthermore
the famous Duncan-Chang model is adopted in consideration of nonlinear properties of soil
and the uniform point distribution mode is selected. At last
comparisons with the results of one-dimensional consolidation method and FEM show that this method is more accurate and satisfying.
