| Abstract: | The subsidence of urban structures exists widely in the large and medium- sized cities in our country. This paper takes the subsidence monitoring of Shanghai＇s river- crossing tunnels as an example,introduces a practice process which makes use of second- grade leveling survey for the subsidence monitoring of the tunnels（ one of the methods of the city subsidence monitoring） and summarizes certain specific methods and experiences of the project of the subsidence monitoring of the river- crossing tunnel. These would make much sense to grasp the laws of the subsidence and forecast the tendency of subsidence. |
