Evaluation of Slope Stability Based on Fuzzy Mathematics with Combination Weighting Method of Game Theory
Published 2021-01-01“…In order to accurately evaluate the stability of the slope and reduce the risk of landslides,taking the Jiangjiatang slope project in Xingshan,Hubei as an example,this paper selects four first-level indexes namely topography and geomorphology,geological structure,rock and soil properties,and occurrence environment and 16 second-level indexes including slope height,joint development,internal friction angle,and atmospheric rainfall to establish a fuzzy comprehensive evaluation model,weights the slope stability evaluation index system by the combination weighting method of game theory based on the analytic hierarchy process and entropy weight method,and obtains the final weight value of the evaluation index by solving the model.The results show that the index weights obtained by the combination weighting method of game theory are between those calculated by the subjective and objective weighting methods,and the evaluation results of slope stability are consistent with the actual situation,which prove that this method is reasonable.…”

Consideration of the Effects of Air Temperature on Structural Health Monitoring through Traffic Light-Based Decision-Making Tools
Published 2018-01-01“…However, although resonance frequency can be used as an indicator of change, misinterpretation is possible since frequency is affected not only by the occurrence of damage but also by certain operating conditions and particularly certain atmospheric conditions. In this study, after analyzing the correlation of resonance frequency values with temperature for one building, we use the data mining method called “association rule learning” (ARL) to predict future frequencies according to temperature measurements. …”
