Monitoring and analysis of East Diaoyutai Station on the 9th line of Beijing subway

Deep excavation engineering is a dynamic and complex system where the soil and the support structure interact. By analysis of information of monitoring and surveying, the distortion of the earth can be learned and the change direction can be forecasted. Deep excavation of East Diaoyutai Station on the 9^th line of Beijing subway is taken as an example, workers inspected earth surface displacement around deep excavation, horizontal displacement of stake body, horizontal displacement of stake peak, and steel brace axis stress on the scene, and then analyzed the data. And then work state of support structure can be mastered at any moment, which can guide the excavation and construction.
