盾构下穿机场滑行跑道经验措施交流

Exchange of the Experience and Measures of the Shield Under Crossing the Airport Taxiway

论文通过前期准备阶段、控制措施、技术总结等各方面阐明某地铁工程中下穿机场滑行跑道中经验控制理论和方法,并介绍施工过程中的动态控制措施。首先详细阐述了盾构掘进过程中控制措施意义重大,并从盾构机的选型方面以及设备维保、掘进参数、渣土改良、同步注浆等方面进行阐述和探讨。论文侧重于技术理论和施工控制的协调,实际施工过程中可操作性强、效果明显。

Through the aspects of preparatory stage,control measures and technical summary and so on,the paper expounds the experience control theory and method of the shield under crossing the airport taxiway in a metro engineering.Firstly,the significance of control measures in shield tunneling is expounded in detail.The selection of shield machine,equipment maintenance,tunneling parameters,residual soil improvement,synchronous grouting and so on are espounded and discussed.The paper focuses on the coordination of technical theory and construction control.In the actual construction process,the operation is of strong maneuverability and the effect is obvious.
