Analysis of Urban Ground Subsidence Hazard Induced by Building Load Combined with Weights of Evidence Model and Deep Learning
摘要
Abstract
Urban ground subsidence hazard induced by building load is analyzed and studied combined with weights of evidence model and deep learning method in the case of southeast subsidence areas,Tianjin,China.We discussed the value controlling or related to ground subsidence of seven major factors:building floor area ratio, structure form,basis form,slope,soil compression modulus,depth to groundwater and groundwater permeability based on weights of evidence model.we proposed the WOE-DBM model by combining the weights of evidence (WOE)with deep Boltzmann machine (DBM),which was applied to draw hazard index figure.The results were validated by receiver operating characteristic (ROC)which show the ground subsidence hazard index generated by this model has a certain "diagnostic"role on land settlement history case in the study area.The AUC is 0.83 that indicates prediction result coordinate with field survey data and certifies the model has high accuracy to ground sub-sidence hazard induced by building load assessment and prediction.The results can be widely used for hazard pre-vention,architecture pattern chosen and land-use planning in the densely urban areas.关键词
