Abstract:Research purposes: The water and mud bursting is one of the common geological disasters in tunnel construction. In the control process of the water and mud bursting, the professionalization management and construction are crucial to the control effect. If the dredging is conducted hastily after the water and mud bursting, the secondary disasters are easy to happen, result in appearance of the bigger water and mud bursting. At the same time, the reliabilities of the mechanized level and the control plan for the water and mud bursting have a large impact on the treatment effect: Therefore, it is necessary to do the research on the professionalization management, safe dredging and blocking, mechanical matching, control plan for the water and mud bursting and its implement to form a set of the control technology used for the water and mud bursting.
Research conclusions: (1)Grouting is an effective method for control of the water and mud bursting of railway tunnel, and the principle of the “grouting reinforcement along with drainage and dropping pressure" should be followed. (2)In order to obtain safe, efficient and economic control effects, a comprehensive control means of the grouting improvement, reinforced anchorage and large pipe roof construction should be adopted with informatization grouting technology and professionalization management.(3)This research results can be applied in control of the water and mud bursting disaster.
