To identify the risk of an asphalt concrete core wall dam under complicated geological conditions

this paper develops systematically a risk index system for such dams from three risk dimensions: three high and one deep complicated geological conditions

asphalt concrete core walls

and traditional earth-rock dams. Aimed at the insufficient fusion of subjective and objective information

this paper uses triangular fuzzy analytic hierarchy process (TFAHP) to determine the subjective weight of risk indicators

criteria importance through intercriteria correlation (CRITIC) to determine the objective weight

and game theory (GT) to calculate the optimal combination weight. An intelligent risk identification method of asphalt core wall dams is constructed based on a TFAHP-CRITIC-GT combined weighting model. Case analysis shows that for an asphalt core wall dam

the risk index weight of its complicated geological conditions accounts for 0.52

which is the most important of its risk factors. Therefore

to identify the risk factors of such a dam accurately

it is of great significance to comprehensively consider its complicated geological conditions and the risk of its asphalt core wall. Our index system and identification method would be applicable to the risk identification and evaluation research of water dams under complicated geological conditions in West China.
