摘要:
本文用特解边界元法及蒙特卡罗边界法计算了弹性地基上重力坝坝踵界面裂缝的断裂可靠度,找出了断裂韧度的均值是影响坝踵界面裂缝可靠度的主要因素,同时指出:区分裂缝的类型对断裂可靠度计算来说是十分重要的。文中还定量分析了地基刚度对裂缝断裂可靠度的影响。计算结果表明:地基刚度对裂缝断裂可靠度的影响甚大,不可忽视。计算还表明:扬压力对断裂可靠性来说仍是一种极为不利的因素。
Abstract:
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.
