摘要
在我国城市建设中,随着城市岩溶富水隧道的修建,岩溶富水隧道的帷幕注浆技术在城市隧道施工中得到了广泛运用。但在岩溶富水隧道施工中,由于对不良地质的超前预报是有限的,当前采用的帷幕注浆具有一定的探索性和盲目性。为了加强对帷幕注浆的指导性和可控性,进行动水动态信息化施工技术的研究是必要的。动水动态信息化注浆设计、施工技术的核心体现在:信息化注浆模型地质数据的更新;注浆方案的优化;现场动态控制。文章介绍了中梁山隧道岩溶富水段帷幕注浆的施工情况,研究分析了帷幕注浆动水动态信息化施工的技术特点和运用效果。
Curtain grouting technology has been widely used in karst and water-rich tunnels. Because of the restric- tions of geological forecasting, there is some uncertainty regarding curtain grouting. To treat dynamie water, it is nec-essary 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.
