Temperature controlling scheme is determined based on the calculation results. Temperature of Lishui Bridge tower foundation is monitored in order to provide evidence for temperature controlling measures including water cooling, heat preservation and moisture retention, etc. Information construction for mass concrete temperature control is implanted. Low thermal cement should be used in mix design of concrete. Adding a certain amount of fly ash into concrete is helpful to control temperature of mass concrete. Cooling water should run through cooling pipe after mass concrete poured, and stop when cooling rate is close to or even greater than 2.0℃/d. If temperature of mass concrete is going up after stopping cooling water, cooling water should run through again. Heat preservation should be done when the inner-surface temperature difference is close to or even greater than 25℃. The temperature controlling scheme is repeated until temperature of mass concrete is stable. Analysis results are introduced. There have been not temperature crack on the surface of tower foundation after mass concrete was poured. Therefore expected target is realized. Engineering practice indicates temperature controlling method and technological process that are introduced in the article are reasonable and effective, and can be used as references for mass concrete construction of bridge tower foundation., authors=ZHANG Yuping, LI Chuanxi, ZHANG Lei, LIU Haikuan, authorsList=ZHANG Yuping;LI Chuanxi;ZHANG Lei;LIU Haikuan, authorCompany=School of Civil Engineering
