大坝坝址处的天然岩基由于其成因不同而具有十分悬殊的物理力学特性,其中尤以基岩的变形模量直接影响重力坝的应力和稳定安全度,一直是重力坝设计中引人瞩目的研究课题。 60年代以来,Zienkiewicz、Varshney以及作者等,先后分别利用弹性力学有限单元法,在坝体混凝土和基础岩石均为弹性的基本假定下,研究了基岩变形特性对重力坝设计的影响。
The natural rock foundation at the dam site has very different physical and mechanical properties due to its different causes. Especially the deformation modulus of the bedrock directly affects the stress and stability safety of the gravity dam. It has been the introduction of gravity dam design Interesting research topics. Since the 1960s, Zienkiewicz, Varshney and the authors have studied the influence of bedrock deformation on the design of gravity dam by using the finite element method of elastic mechanics and the assumption that the dam concrete and the basic rock are elastic.
