| Abstract: | Starting from the impact of deep foundation pit excavation on the tunnel, taking Sujing Road underpass tunnel as an example, through the analysis of the difficulties of foundation pit support construction of open cut tunnel, this paper studies the quality control points of foundation pit support, such as pile foundation construction, steel support construction and crown beam support construction. The key points such as precipitation measurement, deformation monitoring of concrete support and steel support in the monitoring process of open cut tunnel are analyzed. |
