Deep foundation pit engineering is a common form of underground engineering in urban construction.The rationali-ty and safety of its support design and construction are directly related to the development and utilization of underground space and the protection of surrounding environment.With its own advantages,soil nailing wall support technology has been widely used and popularized in the field of deep foundation pit support.The author will systematically discuss the principle,applicable conditions,design method and construction technology of soil nailing wall support,and analyze and evaluate the application of soil nailing wall support technology in deep foundation pit engineering combined with typical engineering ca-ses,in order to provide reference for similar projects.
