To investigate the causes of water leakage at expansion joints of ultra-long water tanks and uncover the temperature and deform-ation characteristics of these tanks,a field monitoring approach was employed using a settling tank at the Fuzhou Xiqu Water Plant as a case study.Meteorological data,temperature at expansion joints,and deformation of the tank structure were monitored for a period of one year,fol-lowed by comparative analysis.The results show that during high temperatures in summer,the highest temperature at a depth of 5cm is 5.4％higher than that at a depth of 10cm,while during low temperatures in winter,the lowest temperature at 5cm depth is 3.9％lower than that at 10cm depth.Under the influence of seasonal temperature differences,the maximum expansion displacement of the tank accounts for 9.1％of the maximum deformation limit of the tank.
