Temperature controlling and monitoring of anchorage floor mass concrete construction of one suspension bridge is introduced. The project has carried out information construction through selection of low heat cement, incorporation of a large number of slag and fly ash, cutting down hydration heat, strict temperature controlling, conservation measures and real-time dynamic temperature monitoring. The monitoring provided the basis for heat and humidity conservation of concrete. There are no temperature cracks appearing on anchorage floor after concrete casted. Results show that the temperature controlling method is effective for anchorage floor construction.
