In subway construction,underpass subway construction and excavation of foundation pits are crucial stages in the entire pro-ject.Under the influence of underground soil disturbance and road load,the road surface and adjacent existing buildings will experience a certain degree of settlement,causing a potential threat.This article combined with practical engineering cases to monitor road surface settle-ment,building settlement and groundwater level changes during subway construction.By analyzing the monitoring results,the trend of road surface,building settlement and groundwater level changes in each stage of construction is determined,and the critical monitoring periods and requirements are determined to improve the efficiency and accuracy of monitoring.And also predicting potential risks caused by settle-ment and changes of groundwater level,in order to take remedial measures in time even if exceeding the limit is discovered,and ensure the safety of the project and subsequent use.
