Urban rail transit tunnel construction is an important part of urban development, and the quality of its construction directly affects the safe and stable operation of subsequent projects. Tunnel blasting is the most common technique in rail transit construction, and blasting control is an important measure to ensure the smooth progress of blasting operations. In the construction of urban rail transit tunnel projects, in order to ensure construction safety and minimize the impact on the surrounding environment, relevant units need to conduct in-depth research on blasting control techniques. Based on this, this paper combines practical engineering cases to conduct specific research on blasting control techniques in urban rail transit tunnel construction, and proposes blasting control measures suitable for urban rail transit tunnel projects, effectively controlling blasting vibrations and noise during subway tunnel construction, providing reference for the construction of urban rail transit tunnel projects in China.
