Modelling 3D strata guided by tables of stratigraphic sequences
摘要
Abstract
It is difficult for modelling 3D strata if different stratigraphic sequences exist among the boreholes. The problem can be solved through following method: deducing the inferior tables of stratigraphic sequences from the main table of stratigraphic sequences which is provided by the survey data with the information of the boreholes, have different stratigraphic sequences from the main table, is the first step. The main table and the other tables become a group of tables of stratigraphic sequences. The relationship that a borehole belongs to which table of the group can find out by using spatial probability analysis and the corresponding relationships between boreholes and tables then are set up. The problems of connecting the boreholes which have different stratigraphic sequences change into the problem of connecting the different tables. A technique that can be used to automatically figure out the corresponding relationship between two tables by searching for maximum count of same stratum is put forward. With this technique, all the tables in the group can be combined into a final table. Basing on it, the algorithm for building layer model is set up. At last, the validation of this algorithm is proved by using it in modelling 3D strata of the slope at Zhu-Yong expressway section K120+030-K120+300.关键词
