This article calculates the reliability of the fracture reliability of the fracture of the elastic base of the gravity dam, and the average value of the fracture toughness is calculated by the special solution boundary metada method and the Monte Carlo boundary method. The average value of the fracture toughness is the main factor affecting the reliability of the cracks of the dam heel interface. At the same time, it is pointed out that the type of dividing seam is very important for the fracture reliability calculation. The article also quantitatively analyzes the effects of foundation rigidity on the reliability of cracks. The calculation results show that the influence of the foundation rigidity has a great impact on the reliability of cracks and cannot be ignored. Calculation also shows that stress is still an extremely unfavorable factor for broken reliability.
