Abstract:With the continuous development of urbanization constructions and underground space excavations, the single and simple support form is difficult to satisfy the design of complex foundation pits nowadays. While the application of multiple support forms become more and more popular in foundation pit engineering. Based on the summary of support forms and the existing problems in the design of foundation pits, the design of a super-large deep foundation pit is taken for an example, and the combined application of multiple support forms in the design of the foundation pit with complex surroundings is introduced and analyzed. It may provide reference for similar projects.
