In order to control the process of cracks in super-long water tank,construction measures for using intermittent expansion strengthening band instead of continuous expansion strengthening band were proposed through statistical analysis on wall cracks of backwash water tank.And experimental application has been car-ried out.The results showed that intermittent expansion strengthening band can further restrict and control the process of the water tank wall cracks.It is appropriate for intermittent expansion strengthening band to be ap-plied intermittently over a period of 7 days～10 days.The actual construction interval time can be adjusted ac-cording to the actual situation,but should not be less than 7 days.This conclusion can be used for deformation joint design of similar water tank and pump house structures.
