The Fuyang River aqueduct is 4 span simply supported pre-stressed concrete structure，and constructed in the early summer，temperature and shrinkage cracks was appeared due to the temperature rising and dropping in early age，and the safety，durability，and service ability of aqueduct structure were affected，and the comprehensive cracking control methods are essential to carried out.temperature and stress distribution were analyzed，and comprehensive temperature control measures were adopted during the construction，it is indicated that the maximum tensile strength is far less than the design tensile strength of concrete and engineering construction quality is ensured during construction.
