Description

Technical Field

[0001] This invention relates to the intersection of road engineering construction technology and computer simulation technology, specifically to a simulation platform and method for road construction in frigid regions. Background Technology

[0002] In the frigid regions of Northeast and Northwest my country, road construction projects face core challenges such as harsh environments, short construction windows, and high technical risks.

[0003] Currently, the effective construction period in frigid regions is only 4-6 months per year. Large-sized variable cross-section high piers need to be constructed in a short period of time. Traditional construction lacks accurate simulation of formwork adjustment and concrete strength growth.

[0004] Furthermore, in frigid environments, concrete undergoes frequent freeze-thaw cycles, and surface erosion is prone to occur at the ice-covered areas of underwater piers during winter. Traditional construction relies on experience to select concrete mix proportions, lacking advance simulation of freeze-thaw cycles, carbonation, and erosion resistance, which requires significant maintenance costs later on.

[0005] Existing construction simulation platforms are mostly designed for normal temperature regions, and suffer from problems such as unsystematic data collection, poor targeting of simulation modules, and insufficient interactivity. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the above-mentioned technical defects and provide a construction simulation platform and method for road engineering construction in cold regions that can simulate the entire process of construction in cold weather and reduce construction risks.

[0007] To solve the above-mentioned technical problems, the technical solution provided by the present invention is: a construction simulation platform for road engineering in extremely cold regions, comprising a simulation host, a simulation module mounted on the simulation host, a data acquisition unit, and an interaction unit;

[0008] The simulation module includes a high pier construction simulation unit, a frost-resistant concrete performance simulation unit, a tunnel fault zone construction simulation unit, and a roadbed settlement simulation unit.

[0009] The data acquisition unit collects geological survey data, meteorological data, existing project case data, and construction material performance data for the area where the road project is located in the frigid region.

[0010] The simulation module performs simulations based on the data information output by the data acquisition unit, and the interaction unit presents the construction process simulation, environmental simulation effects, and monitoring data in a visual interface.

[0011] Preferably, the high pier construction simulation unit simulates the construction process of large-size variable cross-section piers in frigid regions, including: simulating the adjustment process of the variable cross-section template.

[0012] Preferably, the antifreeze concrete performance simulation unit simulates the performance evolution of concrete in a cold environment, including the concrete freeze-thaw cycle process, carbonation process, erosion resistance and alkali-aggregate reaction process.

[0013] Preferably, the tunnel fault zone construction simulation unit simulates the construction process and stability analysis of the tunnel crossing the fault fracture zone, including simulating the deformation of the surrounding rock and the stress on the support, and outputting the tunnel stability evaluation results.

[0014] Preferably, the roadbed settlement simulation unit simulates the filling process of high embankment roadbeds, including analyzing the settlement and deformation characteristics of embankments and foundations under different filling heights and working conditions, and outputting settlement data and deformation characteristic curves.

[0015] Preferably, the data acquisition unit includes a geological data acquisition subunit, a meteorological data acquisition subunit, a case data acquisition subunit, and a material data acquisition subunit;

[0016] The geological data acquisition subunit acquires geological survey data of the area where the road project is located in the frigid region, including stratigraphic distribution, rock and soil mechanical parameters, fault zone location and characteristic parameters;

[0017] The meteorological data acquisition subunit is used to collect multi-year meteorological data for frigid regions, including temperature, wind speed, snowfall, freeze-thaw cycle, and extreme environmental parameters.

[0018] The case data acquisition subunit is used to integrate existing construction case data of road engineering in frigid regions, including high pier construction records, antifreeze concrete application cases, tunnel fault zone construction schemes, and high embankment subgrade settlement monitoring data.

[0019] The material data acquisition subunit is used to acquire the performance parameters of construction materials, including concrete mix proportions, frost resistance grades, mechanical properties of steel, and characteristics of admixtures.

[0020] Preferably, the interaction unit further includes a parameter interaction module;

[0021] The parameter interaction module receives parameter adjustment instructions input by the user and sends them to the simulation module.

[0022] Another aspect of this invention discloses a construction simulation method for road engineering in extremely cold regions, comprising the following steps:

[0023] S1: Collect construction data and classify and transmit the data to the simulation host;

[0024] S2: Clean the transmitted data and generate a standardized simulation dataset;

[0025] S3: Obtain the simulation dataset in modules and execute the construction simulation;

[0026] S4: Visualization of simulation results and interaction with parameters.

[0027] Preferably, S3 includes simulations of high pier construction, frost-resistant concrete performance, tunnel fault zone construction, and roadbed settlement.

[0028] The advantages of this invention compared with the prior art are as follows: This invention collects geological, meteorological, case, and material data of frigid regions by classification and combines them with existing cases to verify the rationality of the data, providing reliable input for simulation. The simulation scenarios in this invention are highly targeted, with special simulation units designed for four core construction scenarios in frigid regions: high piers, frost-resistant concrete, tunnel fault zones, and roadbed settlement. This facilitates the prediction of technical risks before construction and the optimization of construction processes. Attached Figure Description

[0049] Visualization module: Displays the construction process simulation (such as animation of high pier formwork adjustment), environmental simulation effects (such as concrete freeze-thaw erosion effect diagram) and monitoring data (such as surrounding rock displacement curve) in the form of charts (line charts, bar charts, 3D models);
