区间隧道微扰动注浆在郑州地铁中的应用研究

Study on the Application of Micro Disturbance Grouting in Zhengzhou Metro

微扰动注浆工法作为整治区间隧道整体下沉及收敛变形有较好效果的施工工艺,广泛应用于轨道交通区间沉降变形治理工作中。分析微扰动注浆在郑州地铁运营区间隧道收敛变形治理中的具体应用,研究其治理效果,验证了在复杂地质条件下的施工效果及适用性,积累了宝贵的治理经验。

The micro disturbance grouting method is widely used in the settlement and deformation control of rail transit as a construction technology with good effect in the treatment of the overall settlement and convergence deformation of the tunnel.In this paper,through the application of micro disturbance grouting in the treatment of convergence deformation of the tunnel in Zhengzhou metro operation period,the treatment effect is studied,the construction effect and applicability under complex geological conditions are verified,and valuable treatment experience is accumulated.
