软土地基沉降的动态实时预测研究

Study on Dynamic Real-time Prediction of Soft Soil Foundation Settlement

软土地基沉降是受多因素影响的多维非线性系统,各因素的多样性、复杂性和不确定性对系统的影响表现为地基的沉降变形。本研究以灰色模型和BAYES动态模型为基础,建立预测地基土实时变形的动态模型,分别对趋势项和动态项进行预测。以该模型预测某软土地基工程的地基沉降变形,并与实际监测的沉降变形数据进行对比分析,证明该模型对地基工程的实时动态控制具有实用性。

Soft soil foundation sedimentation is a multi-dimensional nonlinear system affected by many factors.The system is influenced by the diversity,complexity and uncertainty of those factors at any moment.The sedimentation deformation is as the final reflection.Based on gray model and BAYES dynamic model,a real-time dynamic prediction model is built.According to some soft soil foundation project,the sedimentation and deformation are predicted.The predicted result and the actually surveyed deformation data are compared and analyzed so as to verify the practicality and validity of the model.
