Abstract :
The technologies of geographic information system(GIS) and spatial information provide a new approach to solve complex problems in geotechnical engineering. This paper presents the design and the implementation of the geotechnical engineering information analysis and computation system (GIACS), in which the techniques of modeling for strata in three-dimensional space play an important role. In addition, a series of spatial analysis algorithms and techniques of the generation of multiple strata, the visualization expression of the strata, the real-time optimal adaptation of meshes, the expression of the body meshes of strata and the acquisition of the meshes of finite element method(FEM) are discussed. Based on the typical slope project in Longtan Hydropower Station, the model of three-dimensional strata founded on grid of multi-variant information is put forward. This study will make it possible for GIS to be successfully applied to geotechnical engineering and will give some useful references to the further researches.
