Abstract

Abstract

Excavation dewatering is an essential part of foundation pit engineering, but it carries many risks. To ensure the safety of the foundation pit excavation dewatering, a comprehensive risk assessment model was established based on neutrosophic enhanced best-worst method (NE-BWM) and technique for order preference by similarity to ideal solution (TOPSIS). Taking an excavation dewatering of foundation pit in Shanghai as a case study, a risk indicator system was constructed to validate the comprehensive risk assessment model, and sensitivity analysis was performed on the evaluation results. The findings show that this method can yield relatively objective and reliable evaluation results, which are consistent with the actual engineering situation.
