Research on the Construction Monitoring for Enclosure Structure of Working well

Working well of nanjing city latitude three pass by river channel project is taken for example. Underground continuous wall was adopted in this project. Detailed monitoring scheme was formulated and lots of date was obtained by foundation pit. The monitoring data changed sharply analysis shows that the maximum horizontal displacement and the maximum strut axial forces is located near the excavation surface and along with the soil excavating. After structure construction, the change of deformation and internal force of enclosure structure gradually became stable. The theoretical analysis and test results are tend to be consistent. But this two have certain differences due to the influence of various factors.
