Application and Numerical Simulation of Key Technologies for Deep Foundation Pit Support

Abstract This paper adopts the key technology “tunnel and underground space support components”, assembles it into a “honeycomb” structure type, expands its application to deep foundation pit engineering, which fully reflects combination of “industry-university-research” theoretical research engineering practical application. can optimize setting lateral components in process, improve current conventional construction technology, has good industrialization promotion value. In this paper, deformation stress–strain analysis each working condition excavation are also carried out through numerical simulation, uplift displacement stress change bottom within safety range control, supporting is far lower than bearing capacity prefabricated components, further verifies practicability reliability innovative technology.
