【摘要】 深层抗滑稳定一直是重力坝设计的关键性问题,由于该问题的复杂性,目前对于分析方法尚无明确和统一的规定。本文在介绍常用可靠度计算方法的基础上,推导了重力坝深层双斜滑裂面的抗滑稳定可靠度计算公式,并用编制的计算程序对弄另水电站非溢流坝段7#坝段进行了可靠度分析。计算结果表明,应用可靠度理论进行重力坝深层抗滑稳定分析是可行并有效的。更多还原

【Abstract】 It is a key problem of stability against sliding of deep foundation in gravity dam design,there are no specific and uniform methods as the complexity of the problem at present.The formulas of reliability for calculating the stability against sliding at deep foundation of gravity dam are deduced based on reliability theory.The reliability of 7th monolith of Nongling hydropower station is calculated by the edited procedure.The calculation result shows that the reliability theory applied for stability against deep sliding of gravity dam is viable and effective.更多还原
