Research on Construction Safety Risk Warning Model Based on Digital Twins
This study integrates digital twin technology and deep learning algorithms to propose a dynamic risk warning model aimed at addressing the challenges of data silos, static analysis, and insufficient quantification of multi factor coupling effects in traditional risk assessment. By building a "physical virtual" real-time mapping digital twin platform that integrates BIM, IoT, and GIS technologies, multi-source data fusion in construction scenarios can be achieved; Design a GCN-LSTM hybrid neural network and combine attention mechanism to explore the risk coupling relation-ship between "human machine environment management"; And quantify the strength of risk interaction based on the N-K model. Empirical research has shown that the accuracy of model warning reaches 92.7%, the false alarm rate is reduced to 6.8%, and the re-sponse time is shortened by 40%, providing theoretical methods and technical tools for intelligent construction safety management.

Digital Twin Platform Integration
The digital twin platform integrates BIM 3D modeling for detailed site representation, IoT sensor networks for real-time data collection (wind speed, tower crane inclination, worker trajectories), and GIS spatial positioning for geological hazard and meteorological data overlay. This creates a "physical virtual" real-time mapping, enabling comprehensive data fusion and dynamic scene mirroring.
GCN-LSTM-NK Hybrid Model
The core of the model is a GCN-LSTM hybrid neural network combined with an attention mechanism to capture spatiotemporal risk coupling relationships ("human machine environment management"). A N-K model quantifies the strength of nonlinear interactions between multiple risk factors, providing a robust method for complex scene recognition and warning.
| Model | Accuracy | False Alarm Rate | Response Time (minutes) | Complex Scene Recognition Rate |
|---|---|---|---|---|
| BP Neural Network | 78.5% | 18.2% | 22 | 55% |
| Random Forest | 85.3% | 12.5% | 20 | 68% |
| GCN-LSTM (This Study) | 92.7% | 6.8% | 15 | 89% |

Improved Identification of Interaction Intensity
Key Risk Factors Identified
Through attention weight analysis, five core risk factors were identified: deep foundation pit enclosure structure displacement rate threshold (>3mm/h), tower crane overload duration (>30 minutes), extreme precipitation events (>50mm in 48 hours), and risk coupling combinations. The model improved interaction intensity identification by 12 times.
Chengdu Chongqing Region High-Rise Projects
This study conducted empirical research on 5 representative high-rise building projects in the Chengdu Chongqing region, covering mountainous super high-rise buildings, plain complexes, and underground space clusters (totaling over 2 million square meters). This regional focus addresses unique challenges like karst landform and high-density construction.
- Achieved 92.7% warning accuracy for complex scenarios in the region.
- Reduced false alarm rate to 6.8%, streamlining construction management.
- Optimized response time to 15 minutes, 40% faster than traditional methods.
- Improved identification of interaction intensity by 12 times for high-risk combinations specific to the region (e.g., "deformation rate of retaining structure >3mm/h + daily increase of groundwater level >0.5m").
Data Collection & Preprocessing
Data was collected from over 2000 IoT monitoring devices (e.g., tower crane sensors, environmental sensors, personnel tags), LOD400 BIM models, and 50000 text data management records (safety logs, inspection forms). This multi-source data underwent preprocessing, including outlier elimination, missing value imputation, and Z-score standardization, ensuring high-quality input for the model.
