| Abstract: | The environmental effects are analyzed and the secondary lining concrete durability is studied in the design for Qingdao Metro Line 3.It is shown in the results that according to the use duration for 100 years,the concrete strength grade is taken as C45 in the inland segment of Line 3 and the water-binder ration is less than 0.40,while they become respectively C50 and less than 0.36 in the near-shore segment.The reinforced concrete cover thickness is also determined respectively for the vehical-moving side ... |
