| Abstract: | Deformation monitoring and alerting technology is of great importance in the process of foundation pit excavation.Based on the monitoring items stipulated in the national codes,the provisions suitable for local features of Henan Province were suggested.Some key issues were discussed,such as the plan and section sketch of pit location,the excavation phase and water-table,the horizontal displacement of pit wall,the settlement of adjacent buildings and so on.Finally,the alerting thresholds were recommended to avoid pit wall collapse. |

| Keywords: | foundation pit deformation monitoring environmental relationship sketch displacement settlement |
