【摘要】 在总结已建工程实践经验的基础上 ,对拱坝的作用不定性、抗力不定性、结构计算模式不定性等进行了分析讨论 ,并最终得出了用分项系数表达的、不同等级建筑物及不同设计状况下的、基于拱梁分载法的压应力控制标准 ,并对该标准进行了可靠度验证更多还原

【Abstract】 Based on summarization to the practice of built projects,this article has find a way to discuss the uncertainty of the action,resistance and calculation mode for the structure,etc.on the arch dam.Finally,a control criterion for the arch dam compression stress is expressed with distribution safety factor to different grade construction works base on trial load method,and the reliability verification to the criterion carried out.更多还原
