| 摘 要： | 重力坝失稳宏观表现为从一种连续性状突然跳跃到不连续性状的突变现象。以突变理论作为研究突变现象的理论和方法，可以为重力坝稳定性分析和评价提供很好的手段和工具。借助坝工领域知识和突变理论，基于大坝安全变形监测资料，以大坝变形时效分量为大坝系统演化的状态变量，研究并构建了重力坝稳定性的尖点突变监控模型，并利用Delphi进行了软件模块的设计和研发，实现借助软件系统对重力坝稳定性的实时监控。

| Abstract: | Macroscopic gravity dam instability is manifested as a catastrophic phenomenon from a continuous to a discontinuous trait. As the theory and method to study the catastrophic phenomenon, catastrophe theory provided excellent approaches and tools for the stability analysis and evaluation of gravity dam. On the basis of dam safety deformation monitoring data, a cusp catastrophe monitoring model of gravity dam stability was established with the dam strain aging component as the state variable of dam system evolution. The software module was designed and developed with Delphi to achieve the real-time monitoring of gravity dam stability. |
