在海洋性气候条件下,空气湿度非常大,在隧道的洞口处,二氧化碳的含量非常高,达到了空气中的五倍以上,导致隧道混凝土的耐久性受到了非常大的影响。在温带海洋性气候的影响下,需要对混凝土原材料选择、配合比和服役寿命等方面进行综合的考量。
In maritime climates, the humidity of the air is very high. At the openings of the tunnels, the carbon dioxide content is very high, reaching more than five times that of the air, resulting in a very significant impact on the durability of the tunnel concrete. Under the influence of the temperate maritime climate, comprehensive consideration should be given to concrete raw material selection, compounding ratio and service life.
