Abstract :
The requirement of urban underground space development of Changchun city has been raised. According to interrelation of the stratigraphic sequence and the transformation of the strata of the adjacent holes, and ground three-dimensional superficial model, a 3D visible model of the quaternary stratum has been established, which the stratum is the target area . The model was established on the basis of bore data, which includes the data of over 2,500 geotechnical and hydrological exploration holes, and more than 50 control holes. All the holes were on the target area of which the total size is 1,156km2. A module of 3D Strata Modeling of GMS software (STRATIGRAPHY MODELING) has been used. Practice proves that they are effectual measures to improve the precision of model, which establishing logical virtual holes with geological data and adopting three-dimensional hypostatic model to construct the geological structure.
