| Abstract: | The paper illustrated by the example of engineering in a sandy cobble ground of deep foundation pit in Beijing Subway Station. The Firstly it discussed the engineering overview, the foundation pit monitoring content, monitoring frequency and monitoring cycler Secondly, it analyzed the surface subsidence , horizontal displacement of pile top, pile horizontal displacement characteristics of the distribution through the excavation around foundation pit soil load change theory; Finally, the monitoring results are summarized by the actual monitoring data, it explained the monitoring results with the theoretical analysis of the dif- ferent and anastomosis of the department using the monitoring the time curve chart, for future similar projects design, con- struction, process engineering safety accident risk transactions and provide a reference. |
