摘要
沪昆客运专线(云南段)尖山隧道岩溶发育带频繁,洞内岩溶水系发育,局部具有承压性,如何选择合理的防排水设计与施工方法,对于保证隧道安全通车运营具有重要的意义。文章结合现场施工实际,总结了防水板挂设焊接、纵向钢边止水带定位、环向止水带安装等方面的施工工艺和技术要求,可为类似工程设计及施工提供参考。
Karst zones with a well-developed Karst water system and partly confined water were frequently encoun- tered during construction of the Jianshan tunnel on the Shanghai-Kunming Passenger Dedicated Line (Yunnan sec- tion). Hence it was extremely important to have a proper waterproofing and drainage design and construction method for ensuring safe tunnel operation. Combined with site situations, the construction technology and technical require- ments for the installation and welding of waterproofing boards, the fixing of longitudinal steel-edge water stops, the installation of circumferential water stops and other measures are summarized in this paper, which provides a refer- ence for the design and construction of similar projects.
