In order to ensure the safety of the subway in the process of excavation, combining with the geographical location and geological situation of the project, with the high-precision automatic monitoring system, it sets up the corresponding monitoring points to protect and monitor the subway near the project, so as to ensure the normal construction of the foundation pit Iron impact is minimized. The monitoring results were in line with the requirements of the specification, providing guarantee for the subsequent construction.

In view of the influence of Metro under construction on the foundation pit excavation of the new commercial service project in the city and in order to ensure the safety of subway in the process of foundation pit excavation, combined with the geographical location and geological conditions of the project in this paper, the corresponding monitoring points were set up to protect and monitor the Metro near the project, so as to ensure the minimum impact on the Metro under the premise of normal construction of the foundation pit. The monitoring results were in line with the requirements of the specification, providing guarantee for the subsequent construction.
