RESEARCH ON DURABILITY OF LINING CONCRETE OF QINGDAO-JIAOZHOU BAY SUBMARINE TUNNEL
Qingdao-Jiaozhou bay submarine tunnel which crosses over/iaozhou bay is underconstruction. The durability of concrete structure should be studied. This paper puts forwardthat the air ventilated tower should be heightened by analyzing the tunnel surroundings,studies some basic durability parameters,such as concrete strength,the permeabilitycoefficient of anti-chloride,the thickness of protective layer and so on,based on the methodof degradation modal,and suggests some durability protective measures,such as raw materialof secondary lining concrete and mating ratio,the construct of waterproof and bailing,thedamp maintenance quality,the construct quality of joint and the force of removal of mould,the monition and detection of construct quality,and so on.
