针对传统的重整化群方法不适合处理一般水工混凝土结构的问题,以正方体单元岩石破碎模型为基础,提出并建立了基于重整化群方法的三棱柱单元混凝土结构整体破坏概率模型,通过不动点计算分析,得到导致结构整体破坏的单元破坏概率临界值。迭代计算结果表明,原胞级数即迭代次数取3即可满足实际工程需要,若3次迭代后整体破坏概率仍较大,则说明单元破坏概率接近临界值,该概率模型可从定量的角度评价混凝土重力坝的整体安全性。
Aiming at the problem that the traditional renormalization group method is not suitable for the general hydraulic concrete structure, the whole failure probability model of triangular prism concrete structure based on the renormalization group method is proposed and established based on the cube rock failure model, Fixed point calculation and analysis, resulting in the destruction of the overall unit damage probability of critical value. The results of iterative calculations show that the number of original cells, ie, the number of iterations, can satisfy the needs of the actual project. If the overall failure probability is still large after 3 iterations, the probability of unit failure is close to the critical value. This probability model can be used quantitatively Evaluate the overall safety of concrete gravity dam.
