Accompanying drawing explanation
Fig. 1 is the principle of work schema of the present invention.
Embodiment
Feature of present invention and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that the understanding of technician of the same trade:
Embodiment: as shown in Figure 1, based on the three-dimensional geological automation modeling method slitless connection geology database of BIM in the present invention, modeling data comes from the geology data such as the cover hole data in prospecting geology database, place individual-layer data, planar cloth hole coordinate, section, modeling personnel only need to carry out the required engineering geology data built in searching database according to construction number index, automatic modeling can be carried out, make the data prediction such as boring differentiation, stratigraphic division without the need to artificial again, specifically comprise the following steps:
Relevant data are imported in prospecting geology data server by prospecting geology prospecting information processing software, prospecting geology database is connected according to configuration file, and utilize the WCF service function being deployed in server end to resolve the prospecting data such as boring, place layering, section, obtain for Revit platform. Wherein, relevant data refer to prospecting geology and borehole data source file, it is possible to comprise the geology data such as cover hole data, place individual-layer data, planar cloth hole coordinate, section.
Revit platform can browse the Back ground Informations such as this engineering the drilling, stratum number and boring point position distribution after getting prospecting geology and borehole data source file from prospecting geology data server at front section of interface, automatically configures the modeling parameters of acquiescence simultaneously. User also can arrange modeling parameters according to the modeling demand of self voluntarily.
The modeling algorithm of Revit platform utilizes Delauny triangulation to set up a main TIN, then the trilateral in main TIN is traveled through by layer, taking demixing point of holing as sample point, with minor increment inverse ratio method and normal stabilizing pile space interpolation matching, obtain the locus of two up and down corresponding trilaterals and build corresponding solid element with the triangular prism scale of construction race of self-adaptation in Revit, affiliated floor number is assigned to this solid element, finally the solid element of identical layer number is spliced to form ground layer entity.
