模糊控制技术不依赖精确的数学模型，利用专家的经验建立控制规则，因而能够有效地解决盾构在施工过程中经常遇到的掘进姿态难以及时调整、地层严重变形甚至塌方等工程事故。在简要阐述了模糊控制技术的基本原理、控制特点及其国内外研究历程的基础上，介绍其在盾构施工过程中的风险评估、地层移动与变形、掘进姿态控制、地质条件判定等方面的应用现状，并对其发展方向进行了展望，以期为模糊控制技术在盾构领域内的应用提供参考。

The posture of the shield machine and the deformation of the ground can be brought under effective control by means of fuzzy control technology on basis of export experiences. In the paper, the basic principles, control characteristics and study in China and abroad of fuzzy control technology are presented. The stateofart of the application of shield tunneling and the development forecasting are presented in terms of risk assessment, ground displacement and deformation, shield machine posture control and geological condition prediction. The paper can provide references for application of fuzzy control technology in shield tunneling in the future.
