Construction method for parallelly overcrossing existing operating tunnel on newly-built open cut tunnel
The invention provides a construction method for a newly-built open cut tunnel to parallelly overpass an existing operation tunnel, and belongs to the technical field of building engineering design and construction. In the construction process of a newly-built tunnel, the adverse effect on the lower existing tunnel during the construction period is reduced by adopting the mode of strictly controlling the single unloading amount, compensating the counter weight load, strictly dewatering as required and automatically monitoring, and the overall anti-floating requirement is met by adopting the mode of adopting the enclosure structure and the anti-floating bracket; therefore, the purpose of ensuring safe operation of the lower existing tunnel in the whole process stage is achieved.
本发明提供了一种新建明挖隧道平行上跨既有运营隧道的施工方法，属于建筑工程设计与施工技术领域，在新建隧道施工过程中采用严格控制单次卸载量+配重荷载补偿+严格按需降水+自动化监测的方式减小施工期对下部既有隧道的不利影响，采用围护结构+抗浮牛腿的方式满足整体抗浮的要求，以达到全过程阶段均能保证下部既有隧道安全运营的目的。
