随着公路市政交通道路的发展,特长隧道施工工程也日益增多,但是在隧道内地质条件较为复杂,很多因素都会直接影响隧道混凝土的耐久程度,这就需要从多方面入手,有效的提高隧道混凝土的耐久性,进而确保隧道的使用寿命。本文将结合实际对特长隧道耐久性混凝土配合比设计与施工控制做了简要论述,希望可以解决一些实际问题。
With the development of highway and municipal traffic roads, the construction of extra-long tunnels is also increasing day by day. However, the geological conditions in the tunnel are complicated and many factors will directly affect the durability of the tunnel concrete. Therefore, it is necessary to start from many aspects and effectively improve the tunnel concrete The durability, and thus ensure the service life of the tunnel. In this paper, we will briefly discuss the design and construction control of the durable concrete mix of long tunnel with the actual situation, hoping to solve some practical problems.
