Research on Invasion Limit Treatment Technology for Deep and Large Foundation Pit Surrounding Structures in Complex Environments
In order to prevent the intrusion of retaining structures into the design clearance of the main structure and prevent dangerous situations such as water,sand,and collapse in the foundation pit,based on the case of a deep foundation pit retaining structure intrusion treatment at a certain station,while ensuring the safety of the deep foundation pit,meeting the requirements of later structural bearing capacity and durability,considering the engineering geology and hydrogeology,the basic situation of the intrusion of the retaining structure is introduced;a treatment plan designed based on the actual situation of enclosure structure intrusion.According to the design scheme,the bearing capacity and crack control calculation were carried out,and the verification results showed that the maximum crack width is 0.105 mm≤[ωMax]=0.200 mm,meeting the requirements for crack control in the regulations.Finally,relevant design and construction measures were summarized,aiming to provide reference for similar projects.
