Abstract Curtain grouting technology has been widely used in karst and water-rich tunnels. Because of the restrictions of geological forecasting, there is some uncertainty regarding curtain grouting. To treat dynamic water, it is necessary to use observational grouting, which is characterized by upgrading the geological data of the grouting model and optimizing the grouting scheme and control of the construction site. This paper introduces the construction of curtain grouting in the water-rich Zhongliangshan tunnel and analyzes the features of observational grouting and its effects.
