Abstract: Based on Wuzhong Road Station of Shanghai Metro Line 15, the internal force monitoring of the structure during the construction period is carried out to capture the structural characteristics of this new type of large span subway station without columns in soft soil. Based on the monitoring data, the basic characteristics of this new type of subway station are understood, and the mechanical response of the key components is summarized. Monitoring analysis shows that this new structure is safe and reliable.
