由于传统方法在预测滑坡地质灾害精度较低,基于此,该文提出基于BIM信息模型的三维滑坡地质灾害预测方法。引入了BIM信息模型的框架,通过最优权重值的确定,完成了三维滑坡地质灾害预测数据的预处理;在BIM信息模型的背景下,利用随机差分方程建立了预测数据之间的依赖关系,通过建立预测序列的数学模型,得到了地质灾害预测的目标函数,完成基于BIM的预测序列模型的构建;通过三维滑坡地质灾害预测算法设计,实现了基于BIM信息模型的三维滑坡地质灾害预测。
Because of the low accuracy of the traditional method in predicting landslide geological hazards,a three-dimensional landslide geological hazard prediction method based on BIM information model is proposed.The framework of BIM information model is introduced,and the preprocessing of 3D landslide geological hazard prediction data is completed by determining the optimal weight value.Under the background of BIM information model,the dependence relationship between prediction data is established by using random difference equation,the objective function of geological hazard prediction is obtained by establishing the mathematical model of prediction sequence,and the prediction sequence model based on BIM is completed.Through the design of 3D landslide geological hazard prediction algorithm,the method based on 3D landslide geological hazard prediction algorithm is realized.The prediction of the three-dimensional landslide hazard of BIM information model.The experimental results show that the geological hazard prediction method based on the BIM information model has higher prediction accuracy compared with the geological hazard prediction method based on data mining.
