Abstract：With thecontinuous breakthroughs in the scale and depth of deep foundation pit projects，the requirements of complex geological conditions，surrounding environments and construction technologies have increased the diffculty of deformation control of deep foundation pit supporting structures，and engineering acidents caused by deformation occur from time to time.it is urgent to conduct in-depth research on deformation characteristics and countermeasures.this study focuses on the deformation characteristics of deep foundation pit supporting structures in buildinggeotechnical engineering，analyzes theirdeformation laws under differentgeological conditions，construction technologiesand external loads，and discusss the impactof deformationon the surounding environment and engineering safety.combined with practical situations，targeted countermeasures such as optimized design and scientific constructionare proposed，aiming to provide theoretical and practical references for improving thestabilityof deep foundation pit supporting structures and ensuring engineering safety.
