| Abstract: | The asymmetric settlement of ground surface caused by the excavation of tunnel in the subway is a key problem in engineering.The settlement trough of saturated loess tunnel with double lines, was monitored by the water level.The surface settlement of the top of right and left tunnels with 30 meter distance between two excavation surfaces changing with time and the characteristics of settlement troughs of single tunnel and double tunnels were analyzed with the monitoring results.It is shown that the settleme... |
