基于强滑移岩溶强发育地区特点构建下的广西某地地铁盾构施工探索

Exploration on Shield Construction of a Subway in Guangxi Based on the Characteristics of Strong Slip Karst Area

应用盾构法进行地铁工程施工时如果遇到强滑移岩溶强发育地区,盾构隧道往往需要穿过岩溶洞穴,对此应采取注浆方式来充填溶洞,这对施工技术提出了很高的要求。施工单位必须不断积累施工经验,充分掌握强滑移岩溶强发育特点,合理运用相关的施工技术工艺,保证施工的质量和安全。

When the shield method is used in the subway construction,the shield tunnel often needs to pass through the karst cave if it encounters the area with strong sliding karst development.Therefore,the grouting method should be adopted tofill the karst cave,which puts forward high requirements for the construction technology.The construction unit must continuously accumulate construction experience,fully grasp the development characteristics of the strong slip karst,and reasonably apply relevant construction technologies to ensure the quality and safety of construction.
