Abstract:Research purposes:The calculation and analysis were made with the stratum structure model and load structure model to control the deformation of arched structure near the large deep foundation pit,and the rational protection measures and the support system were chosen for the deep foundation pit near the arched structure.
Research conclusions:The monitoring data showed that by control of the displacement of the inclined arched pile foundation of the terminal,the good effect achieved to make the deep foundation pit engineering in safe and stable state.It proved the rationality and stability of the design. For the nearby structure,the compressed deformation of the soil could be redeuced by reinforcing the foundation to achieve the obvious effect of controlling the deformation of the structure,and the transmission of the horizontal thrust into the support system for foundation pit could be cut by the insulation pile to get the good control effect of the deformation of the foundation pit.It was necessary to establish the comprehensive and rigorous monitoring system during construction so that the monitored data could be feedback to direct the construction.It not only guaranteed the safety and stability of the foundation pit,but also controlled the influence on the nearby environment and reduced the influence of the construction on the environment around the inclined arched foundation of the terminal.
