Abstract：Takinga deep foundation pit project of a metro in Gongshu Districtof Hangzhou cityas theresearch background，this paper systematically studies the influence control technology of pile-anchor support structures on adjacent buildings.Through the integration of key technologiessuch asdouble casing folow-up hole forming，BIM pileposition recheck and dynamic stresscompensation，an information-basedcollaborative management platform is constructed.Monitoring data show that the maximum horizontal displacement of the support piles is 18.7 mm，the average value of anchor cable prestress loss is 6.3% ，thedifferential settlement of adjacentbuildingsis 0.82‰ ，and the peak valueof surfacevibration velocity is1.9cm/s，allof which arebeterthanthe design controlvalues.The research results provide an effective technical reference for deep foundation pit projects in urban dense areas.
