摘要
Stablishment of Three-dimensional engineering geology strata model could observe the geological structure of the urban underground space,and provide a auxiliary reference for the geotechnical investigation,engineering design and construction.Based on the investigation datas,use GOCAD to construct the three-dimensional engineering geology strata model of local sections of the study area.It is proved that GOCAD is convenient to draw and visualized well.The three-dimensional engineering geology strata model constructed with GOCAD could truly show the actual situation.It is feasible to use this software in geotechnical investigation.
