摘要
提出了两种界定重力坝的极限承载能力的方法 ,其一为坝体内的屈服破坏区是否贯通上下游坝面 ,称为屈服区贯通判别法 ;其二从稳定性理论出发 ,利用能量原理给出了重力坝的极限承载能力判别式 ,称为能量法 .运用两种方法对一实际工程算例作了分析对比 。
Two methods for estimating the ultimate bearing capacity of gravity dam are studied. The first method is to see whether or not the yield area across the dam. The second method called energy method is to define the ultimate state of the dam. Aiming at a real project, the example is given. It is found that the second method usually gets the lower result.
