倾斜荷载作用下层状地基的极限承载力

倾斜荷载作用下层状地基的极限承载力 English Version

摘要: 对位于层状地基上的水工建筑物,特别是位于缓倾斜角软弱夹层上的建筑物,在验算建筑物连同地基的稳定性时,通常假定滑动面是由两个斜面所组成。本文参考模型试验中地基破坏的情况,假定滑动面由三段组成,应用库仑破坏准则,导出地基极限承载能力的近似计算公式。

Abstract: It is generally assumed that the sliding surface is composed of two inclined planes when we check the stability of a hydraulic engineeing structure and its layered foundation, especially the weak intercalated foundation at a slight slope angle. Now the author, having referred to the failure in the model test according to Coulomb's criterion, offers an approximate formula of the ultimate bearing capacity of a foundation on the assumption that the sliding surface consists of three segments.
