Abstract: Based on the complex geological conditions of Tianxing reservoir, such as high slope at the dam abutment, medium-sized landslide at the left dam abutment, soft shale in the dam foundation, and leakage in karst zones, risk levels were identified through hazard identification and risk assessment dur ⁃ ing construction. Risk prevention and control measures were proposed, and a three-in-one intelligent construction risk prevention and control system of "intelligent monitoring, digital twin and dynamic regu ⁃ lation" was constructed. An "AI+BIM+GIS" model was established to improve the efficiency of precise risk control and construction quality. The research results can provide reference for water conservancy intelligent management, intelligent construction and digital twin to improve safety risk control under complex geological conditions.
