High-slope construction dynamic simulation method based on BIM (Building Information Modeling)

Abstract

The invention relates to a high-slope construction dynamic simulation method based on BIM (Building Information Modeling). The method includes the steps that through a BIM platform, slope survey and design achievements are integrated, excavation, supporting process and progress information is dynamically collected in real time, and safety monitoring data are dynamically collected; comprehensive image showing and dynamic simulation are achieved through the parametric modeling technology; an excavation and supporting construction progress image and distribution of supporting achievements are dynamically shown, and the safety monitoring state is synchronously shown; on the basis, the slope supporting following and lagging condition is tracked; and on the basis of engineering portions, influences of lower-layer excavation and supporting construction on the safety monitoring state are analyzed. The method can dynamically and visually show the construction progress, a dynamic excavation, supporting and safety monitoring image at any stage can be reflected, dynamic process simulation based on the time axis is achieved, contrastive analysis is performed on a lower layer excavation image and an upper layer supporting image, contrastive analysis is performed on the changing law between the safety monitoring achievement and an excavation and supporting image, and slope safe and stable state judgment is made under the assisting of contrastive analysis performed on the changing law.

Description

technical field [0001] The invention relates to a dynamic digital construction simulation during a construction period, in particular to a BIM (Building Information Model)-based dynamic simulation method for high slope construction. Background technique [0002] High slope construction is very common in large-scale water conservancy and hydropower projects. High slope treatment construction mainly includes slope excavation, support engineering, progress control during slope construction, and slope dynamic stability and structure during construction. Safety evaluation is the core of slope treatment engineering management, and timely follow-up of support during construction and the realization of dynamic safety monitoring and evaluation are important technical means and measures to ensure project progress and safety. [0003] In slope construction, it is necessary to ensure the structural stability of the slope construction process while ensuring the construction progress, so ...

Problems solved by technology

Traditional analysis methods include burying safety monitoring instruments (anchor cable stress gauges, multi-point displacement meters, displacement observation piles, etc.) for dynamic safety monitoring. Safety evaluation, optimizing the construction plan according to the evaluation results, adding support methods, etc.; however, these methods are not intuitive, cannot realize the integrated analysis of progress and monitoring results, and there are large deviations between the simulation calculation results and the actual situation.
