Deformation control method for newly-built structure above rail transit operation tunnel
A deformation control method for a newly-built structure above a rail transit operation tunnel is characterized in that an adjustable axial force anchor cable is combined with a core control system of a pipe curtain, the process is mature, implementation can be completely carried out, the operation difficulty is very low, active and fine adjustment of the axial force of the anchor cable is realized, and data feedback is provided by combining monitoring points on a bottom plate, a rail and a side wall of the operation tunnel; the vertical deformation of the existing line can be adjusted in real time, so that a rail transit structure is always in an optimal state, which cannot be achieved by an existing upward crossing scheme, small clear distance, long distance and smooth upward crossing of an operation tunnel become possible, and effective combination of an active control system, foundation pit supporting and an anchor cable permanent protection system is realized. The vertical shaft serves as a supporting and retaining structure of a foundation pit of a newly-built structure while providing a pipe curtain driving space and an anchor cable device mounting space. After construction is completed, the top of the vertical shaft is blocked, permanent protection of the anchor cable device is achieved, the interior of the whole system is effectively connected, and engineering investment is reduced.
一种轨道交通运营隧道上方新建结构的变形控制方法，其通过可调节轴力锚索结合管幕的核心控制体系，工艺成熟，可完全落地实施，操作难度很小，实现锚索轴力的主动、精细化调节，结合运营隧道底板、轨道与侧墙上的监测点提供数据反馈，可对既有线竖向变形进行实时调节，使得轨道交通结构始终处于最优状态上，这是已有的上穿方案不能做到的，使得小净距、长距离、顺行上穿运营隧道成为可能，实现了主动控制体系、基坑支护、锚索永久保护体系的有效结合。竖井在提供管幕打设空间、锚索装置安装空间的同时，兼做新建结构基坑的支挡结构。施工完成后，竖井顶部封堵，实现了锚索装置的永久保护，整个体系内部有效衔接，降低了工程投资。
