THE APPLICATION OF THREE DIMENSIONAL GEOLOGICAL MODELING IN A DREDGING PROJECT

摘要

The analysis of dredging soil properties is vital and often difficult in dredging projects. The traditional geologic description and explanation of the dredging material has difficulty in achieving any direct-viewing and therefore the distribution characteristics of quantities and the spatial distribution of various soil layers underground cannot be shown. So the TianJin Dredging Company developed "VGeoDredge" which is a software with the 3D geological modeling function. It can be linked to the different dredging materials associated with dredging engineering in the 3D spatial relation mode by using the modules of topography, stratum and dredging borders. This thesis establishes one dredging engineering 3D geological model which not only supports for the comparison and selection for the dredging design directly, but is more convenient for saving investment, technical support for the construction organizing and optimizing the construction scheme. The application of the "VGeoDredge" boosts the Intuitive aspects and veracity of the geological analysis and offers a convenience to dredging works.
