Accident prediction of project construction based on gray system theory

Author(s): Xiaoming You

In engineering practice, security incident in real terms is a gray system, so it is possible to predict the accident using gray system theory. In this article, we established the prediction model for pit deformation based on gray system theory, and predicted the pit deformation in future adopting actual project monitoring data. The results are in good agreement with the measured values, indicating the prediction model has good accuracy and has positive significance in guiding informationizaton construction of excavation engineering. We establish the metabolism model to improve the accuracy of the prediction model. Practice has shown that the accuracy of the metabolism model is higher than that of the old information model; the predicted results are consistent with the measured data
