整体式连拱隧道渗漏水影响因素研究

连拱隧道由于其在整体线形等方面的优势,在工程中已得到广泛应用,但在已建整体式连拱隧道中均存在不同程度的渗漏水现象,故探究整体式连拱隧道渗漏水影响因素可为其渗漏水治理及创新发展等方面提供依据.以某整体式连拱隧道渗漏水病害为例,通过实地调查隧道渗漏水现状,具体分析隧道渗漏水原因,并结合层次分析法分析各影响因素的主次关系.结...

Research on Influencing Factors of Leakage Water in Integral Multi-arch Tunnels

Thanks to advantages in integral alignment, etc., multi-arch tunnels have been extensively applied in projects. However, leakage water in different degrees exists in constructed integral multi-arch tunnels, so research on influencing factors of leakage water in integral multi-arch tunnels can provide bases for treatment of leakage water and innovative development, etc. This paper based on leakage water disease of some integral multi-arch tunnel as an example definitely analyzes causes of leakage water through field investigation for status quo of leakage water in the tunnel and analyzes primary and secondary relations among different influencing factors in combination with the Analytic Hierarchy Process. The result shows that problems such as design defects of integral multi-arch tunnels themselves and poor management for construction, etc. are major causes of leakage water in integral multi-arch tunnels.
