Abstract: The subsidence of the ground monitoring and control is the most critical issues in the subway tunnel shield construction. Based on a subway shield tunnel construction monitoring technology as an example, analyzes the monitoring project, method, frequency, alarm, control standard, data processing and feedback, such as technology, discusses the factors influencing the surface settlement of shield construction process and construction control technology. The research results in the process of construction of similar projects in the future construction monitoring and control has a reference value.
