摘要
米家沟隧道是位于新建铁路神木至延安北段上的一座单线隧道。该隧道由于围岩破碎、节理发育、水平基岩层裂隙水渗透性强,以及设计与施工等方面的原因,主体工程完工后,隧道出现渗漏水现象。文章在分析了渗漏水原因的基础上,详细地阐述了治理渗漏水所采用的材料及其施工方法,隧道达到了不漏、不滴、不渗的治理效果。该隧道的渗漏水治理措施可供其他隧道借鉴。
Mijiagou tunnel is a single track railway tunnel located at the north section of Shenmu ~ Yanan railway. After the main structure has been completed, it has found that water infiltration had occurred in the tunnel because of the fractured surrounding rock, developed joint, strong water infiltration in the crack of horizontal bedrock and some reasons relative to design and construction. In this paper, it analyzes the reasons to cause water infiltration and describes the material and construction method to deal with this in detail, which brought about a good result. Reference can be taken from this by the similar projects in the future.
