摘要
本文针对重力坝岩基的受荷变形特征及可能破坏形态,就无量纲分析、破坏准则、破坏后效以及应力场与渗流的耦合进行了分析探讨,提出了模拟坝踵裂缝的“裂缝法”,并利用所研制的坝基破坏全过程动态仿真程序进行了算例计算。
This paper gives a research and a discuss to the non-dimensional analysis, failure criteria, post-failure effects, and coupling percolation with stresses in accordance with the characteristic of deformation and the possible failure formation of gravity dams on rock foundation, a 'crack method' for digital tracking the crack at the dam-heel is put forward. a FEN computer programme in order to simulate the whole failure course of gravity dam of foundations is prepared and used for example calculations.
