Abstract Abstract：Research purposes：Aiming at the open and merge between solid track bed and foundation base of the enriched tunnel in the process of the railway operation, the causes of diseases is analysed, reasonable management measure is taken, which is used to plug underground water and grout the disease area, so as to ensure the structure safety of the process of the railway operation.
Research conclusions：Through the practice of construction, the method of composite anchor anchoring and quantitative amount pressure grouting which is used to cure disease is viable. The result of altitude monitoring shows that there is no obvious deformation happens before and after grouting construction, the grouting pressure can satisfy with the line safety control requirements. The result of dynamic monitoring results of the solid track bed when there is the train pass by shows that solid track bed is in a stable state, there is a good reinforcement effect in the disease area. The results of the study can provide a reference for similar enriched water tunnel diseases treatment.

Key words： Key words: solid track bed foundation base disease treatment anchor grouting
