摘要
城市盾构隧道多建在建筑物高度集中地区,周边建筑的施工往往会对盾构隧道造成一定的影响。该文以天津某运营的地铁盾构隧道为背景,探讨了微扰动注浆施工引起的侧向挤压力对地铁盾构隧道的收敛影响,并对微扰动注浆施工技术参数、施工方法、监测手段等方面进行了简要的说明,重点分析了不同情况下注浆对盾构隧道收敛的影响。
The urban shield tunnels are mostly built in highly concentrated buildings area.The constructions of surrounding buildings will have a certain influence to the shield tunnel In this paper,taking an operating metro shield tunnel in Tianjin as the background,the effect on the metro shield tunnel convergence by the lateral extrusion pressure caused by microperturbation grouting is discussed.The technology parameter.construction method and monitoring measure of microperturbation grouting are explaned briefly. The effect on shield tunnel convergence by grouting under different conditions are analysed importantly.
