Prediction Algorithm for Construction Deformation of Tunnel Undercrossing Buildings
Due to the construction process of tunnel undercrossing buildings is relatively complex,most of the traditional building construction deformation early warning systems are based on 2D geographic information systems,which often has disadvantages such as weak visualization ability and poor reliability of model prediction accuracy.Therefore,a tunnel undercrossing building construction deformation prediction algorithm based on improved BIM is proposed.By analyzing the settlement deformation of the building during construction,the deformation vector of the building construction node is obtained,the 3D geological BIM model is built,and the deformation vector of the building node is input into the 3D geological BIM model.By superimposing the dynamic volumetric grid 3D space field data on the 3D BIM geological model,the data is not only expressed in ascending dimensions,but also solves the shortcomings of the weak real-time and collaborative expression of the traditional static BIM geological model,Complete the prediction of the construction deformation of the tunnel undercrossing buildings.The experimental results show that the proposed method can accurately predict the bending deformation of the building wall under the tunnel,and has high prediction accuracy.
