混凝土重力坝变形博弈监控模型研究

Study on game monitoring model of concrete gravity dam deformation

传统的重力坝安全监控模型考虑了水压、温度及时效等外荷载的作用,尚不能反映出大坝材料与结构特性的影响。基于博弈思想,提出大坝变形的博弈参与者,研究分析了大坝变形与大坝材料、大坝结构特性等抗因素的关系,构建了大坝安全监控博弈模型的具体表达式。工程实例分析表明,本文所提出的博弈模型能够更好地模拟大坝的变形过程。

For the traditional safety monitoring model of concrete gravity dam, only the effects of the external loads such as the water pressure, temperature, time efficiency, etc. are considered, which cannot reflect the influences from the materials and the structure characteristics of the dam body yet. Therefore, based on the game concept, the game participants of dam deformation are put forward herein, and then the relationship between the dam deformation and the relevant resistant factors, e.g. dam con- struction materials, dam structure characteristics, etc. is studied and the specific expression of game monitoring model for the safety of concrete gravity dam is established as well. The analysis on actual case shows that the dam deformation process can be more accurately simulated by the game monitoring model.
