Abstract: In the paper,the method of sectionnode control is first proposed to solve the problem of 3D mesh autogeneration in FEM analysi s when geological strata are complicate and largescale underground grottos are excavated.The geological exploratory sections are used as chief control section s,in which a small amount of data preparation is needed.The 3D mesh is generat ed in the whole calculating region by means of different mergences,linkages and interpolations.Several engineering calculation illustrations show that this meth od is simple,more applicable and efficient.
