The　development　of　underground　spaces　in　mega-cities　necessitates　understanding　the　interaction　among　various　underground　structures.　Soil　acts　as　the　fundamental　medium　in　bearing　and　transmitting　forces　during　the　construction　of　these　structures.　In　shield　tunnels,　the　deformation　of　adjacent　soil　is　a　primary　concern.　or　underground　structures　with　piled　raft　foundations,　this　deformation　directly　impacts　the　foundation＇s　bearing　capacity　and　causes　differential　deformation.　This　consideration　becomes　especially　crucial　for　large-diameter　shield　tunnels　when　intersecting　with　piled　raft　foundations.　To　address　this　issue,　the　study　examines　a　case　of　a　mega-diameter　shield　tunnel　intersects　a　piled　raft　foundation,　which　is　the　built　for　an　underground　railway　station.　The　research　focuses　on　soil　deformation　between　the　tunnel　and　the　structure　during　construction,　analyzing　the　variation　of　pile　neutral　points　across　the　foundation　based　on　soil　deformation.　A　method　is　proposed　to　rapidly　predict　incremental　negative　frictional　resistance　of　piles　due　to　tunnel　excavation,　guided　by　soil　deformation.　The　study　clarifies　the　specific　range　of　tunnel　excavation＇s　influence　on　pile-bearing　capacity,　offering　practical　insights　and　potential　theoretical　guidance　for　similar　future　projects.
