Structural Health Monitoring (SHM) is becoming the fourth driving force of engineering science and technology progress, in addition to the basic theory, numerical simulation and model test. In this paper, a definition of dam SHM is presented, its basic connotation is analyzed, and the general problems in existing researches are summarized. Then the sensitivity analysis of the static performance of concrete gravity dam is reviewed. For a hypothetical concrete gravity dam, a preliminary nonlinear finite element model is established. By means of the variance-based global sensitivity analysis method, phenomenological analysis of the static performance of the dam is carried out from three different horizons. And then the results are discussed in detail according to the common components of SHM. Overall, this paper provides a framework for sensitivity analysis of dams, or a way to explore the complexity of the dam system. In the long run, this paper should still be positioned as a generic and qualitative study in view of the complexity of dam system. There are still many issues as pointed out in the text need to be further understood and studied, and sensitivity analysis is a good tool.

除了基本理论，数值模拟和模型测试外，结构健康监测（SHM）正在成为工程科学和技术进步的第四动力。本文提出了大坝SHM的定义，分析了大坝SHM的基本内涵，总结了现有研究的一般问题。然后回顾了混凝土重力坝静力性能的敏感性分析。对于假设的混凝土重力坝，建立了初步的非线性有限元模型。借助基于差异的全局灵敏度分析方法，从三个不同的角度对大坝的静态性能进行了现象学分析。然后根据SHM的通用组件详细讨论了结果。总体，本文为大坝的敏感性分析提供了框架，或者为探索大坝系统的复杂性提供了一种方法。从长远来看，鉴于大坝系统的复杂性，本文仍应作为一般性和定性研究。本书中指出的许多问题仍然需要进一步理解和研究，敏感性分析是一个很好的工具。
