摘要
本文将混凝土材料视为理想弹塑性材料，混凝土的抗拉、抗压强度及温度荷载视为随机变量，用分载位移法分析拱坝开裂直至破坏的概率．并用轴弯复合屈服状态建立极限状态方程．
In this paper the concrete is regarded as ideal elastic-- plastic material and its tensile strength and compressive stength as well as temperature are considered as random variables.The limit--state equation is established by using load distribution--stiffness method with axial compression and bending combined yield limit condition is to be considered.The probability of a crack develop into the collapse of arch dam is also analysed.
