Embodiment
[0016] Example: as figure 1 As shown, the method for realizing rapid parametric 3D modeling of foundation pits using BIM technology in this embodiment includes the following steps:
[0017] 1) The 3D composite BIM profile of the generalized foundation pit enclosure structure, this 3D composite profile is the basic unit (unit component) of foundation pit modeling, which satisfies the principle of linear distribution, can be adjusted by parameters, and can be created once and reused. Parametric adjustment refers to the ability to adjust the specific structural parameters of the 3D composite BIM section of a single envelope structure.
[0018] Generally speaking, the foundation pit envelope structure can be generalized into different section units. The basic procedure of the foundation pit envelope structure design is to select, calculate, and adjust the parameters of different sections, and the section unit of the foundation pit can be It is generalized into a linear distributi...

The invention relates to the technical field of foundation pit design in geotechnical engineering, in particular to a method for realizing rapid parametric three-dimensional modeling of foundation pits by using BIM technology, which is characterized in that: using BIM technology to generalize a foundation pit enclosure structure into a parameterizable The controlled three-dimensional profile is then arranged according to the principle of the linear distribution of the foundation pit edge of the foundation pit enclosure structure and parameterized setting is performed on the three-dimensional profile, and the parameterized setting satisfies the requirements of the size of the foundation pit. requirements, so as to realize the three-dimensional modeling of the foundation pit. The advantages of the invention are: (1) The three-dimensional composite BIM profile of the foundation pit can be controlled by parameterization, and the model can be automatically adjusted by adjusting parameters; (2) The three-dimensional composite BIM profile of the foundation pit has the characteristics of reusability, and can be permanently used for one-time creation. Different models can reduce repetitive labor and improve efficiency; (3) The overall BIM model of the foundation pit can be quickly established, and different schemes can be adjusted according to the design parameters.
Description
technical field [0001] The invention relates to the technical field of foundation pit design in geotechnical engineering, in particular to a method for realizing rapid parametric three-dimensional modeling of foundation pits by utilizing BIM technology. Background technique [0002] The traditional deep foundation pit design, construction, monitoring and other links are relatively independent, and two-dimensional drawings and data charts are used as the transmission medium at each stage. With the continuous development of urban foundation pits in the direction of deep, large and complex, traditional methods are becoming more and more inadequate for the requirements of deep foundation pit risk control, environmental impact analysis, complex working condition expression, monitoring time history change analysis, etc., especially the surrounding environment is complex. For deep foundation pit projects with complex strata and complex construction processes, in the traditional two...
