摘要
辽宁省大伙房输水隧洞TBM2标段独头开挖长度超过8km,贯通精度的控制是工程施工的难点之一。本文对贯通误差、控制测量实施方案进行了详细研究,通过控制测量措施和方案的有效实施,实现了该标段隧洞的高精度贯通。大伙房TBM2标输水隧洞高精度贯通为我国以后做好长大隧洞控制测量方面积累了经验。
The single excavation length of TBM2 bid section exceeds 8km for the Dahuofangwater conveyance project in Liaoning Province, the control of holing-through precision is one of the difficulties in engineering construction. The paper studies in detail the implementation scheme of the holing-through error and the control measurement. The high precision holing-through of the tunnel in this bid section is realized by the effective implementation of the control measurement measures and schemes. The high-precision holing-through of water conveyance tunnel in TBM2 bid section of Dahuofang water conveyance project could accumulate experience for the long and large tunnel control measurement for the future of China.
