Method of interaction between 3D design of underground cavern group and simulation of construction progress

Abstract

The invention belongs to the field of dynamic visual simulation of water conservancy and hydropower construction courses and aims to implement automatic updating of dynamic visual simulation analysis results of an underground cavern group construction course, increase efficiency of three-dimensional modeling and simulation analysis and master construction progress more easily. The invention adopts the technical scheme of a method for three-dimensional design and construction progress simulating interaction of an underground cavern group. The method comprises two aspects that firstly, model parameters are modified, a model is updated automatically, corresponding changes happen to simulation input parameters, simulation calculation is implemented again, and dynamic visual simulation analysis results of a construction course are updated synchronously according to a new simulation progress plan; and secondly, simulation parameters are amended, the simulation calculation is implemented again, corresponding changes happen to the model parameters simultaneously, the model is updated automatically, and the dynamic visual simulation analysis results of the construction course are updated synchronously in combination with a new simulation progress plan. The method provided by the invention is mainly applied to occasions concerning dynamic visual simulation of water conservancy and hydropower construction courses.

Description

technical field [0001] The invention belongs to the field of dynamic visualization simulation of water conservancy and hydropower construction process, and specifically relates to the interaction of three-dimensional visualization modeling of underground cavern groups and construction progress simulation. Background technique [0002] The underground caverns are arranged underground, the construction space is very limited, and the caverns are large in scale and the geological conditions are changeable, so the construction process is extremely complicated. How to make construction decisions accurately and quickly, and realize scientific schedule arrangements in terms of time and space, is a matter of great concern to project managers. At present, the most effective analysis method is to apply scientific visualization technology to the entire construction process of underground caverns Dynamic visualization simulation analysis.

Zhang Jiachi [5] A method based on BIM (Building Information Modeling, Building Information Modeling) simulation model and on-site construction interaction is proposed. This method can detect and deal with problems in the construction stage in time, so as to adjust the simulation model or on-site construction progress, so that the simulation model can not only Theoretically, it can support the construction of the building to be built, and it can also control the construction progress during on-site construction, but this method can only be applied in the construction process, and it is impossible to simulate the changes in the construction process according to the changes in the design data during the design stage; Xiao Guiying [6] Taking the hull model as the object, the research on the interaction technology of the hull model between the ship CAD design software TRIBON system and the CATIA system based on user data storage files is carried out. The data exchange of the panel frame only realizes the one-way transmission of the data of the hull model from the TRIBON system to the CATIA system, and the two-way interaction between the data transmission between the TRIBON system and the CATIA system has not yet been realized; JIN Ping [7] The arch dam visual modeling system is developed based on the CATIA platform, and the VB (Visual Basic) program is used for secondary development to realize data exchange and processing between modules. Users can input parameters through interactive design to establish an arch dam model. This method is very good Realized human-computer interaction and parametric modeling, but only realized the visualization of the modeling process, did not combine the 3D model with the construction progress of the arch dam to realize the dynamic visualization of the construction process; Zhong Denghua et al. [8] CATIA is introduced into the construction simulation modeling of core rockfill dam, and a CATIA-based 3D visual interactive system platform for core rockfill dam is constructed. This method combines 3D design with construction progress simulation, and realizes the 3D model of the construction scene well. Two-way information exchange with the construction simulation schedule, but the interactive design between 3D design and construction simulation has not been realized, and the two-way automatic update of the 3D model and the schedule cannot be achieved

[0006] To sum up, there is currently no research that combines 3D design with construction progress simulation to achieve two-way interaction between the two, and can be applied to engineering design and construction phases at the same time.
