The cast-in-place tunnel structure of the north shore project of Dalian Bay subsea tunnel serves as the north exit of the entire tunnel and is constructed by in-situ cast-in-place technology.Based on engineering examples,this paper introduces the practical application of temperature control measures for mass concrete with cast-in-place tunnels,including concrete mix design,raw material temperature control,concrete production and preparation,mold temperature control,reducing temperature stress through circulation cooling water pipe and intelligent temperature control,and later curing to reduce the risk of concrete cracking.It provides reference for the construction of similar large volume high performance concrete in the future.
