Description

Slope protection device for underground foundation pit of building engineering

Technical Field

Background

As a structural system, the foundation pit support should meet the requirements of stability and deformation, namely the requirements of two limit states, namely a bearing capacity limit state and a normal use limit state, which are generally specified. The limited bearing capacity state refers to the state of support structure damage, toppling, sliding or peripheral environment damage for foundation pit support, and the instability in a large range occurs. The general design requirement is that the supporting structure is not allowed to assume such extreme conditions. The limit state of normal use refers to deformation of the supporting structure or excessive deformation of the surrounding soil body caused by excavation, which affects normal use but does not cause structural instability. Therefore, the design of the foundation pit support has enough safety factor relative to the extreme bearing capacity state, so that the support cannot be unstable, and the displacement is controlled under the condition of ensuring no instability, so that the safe use of surrounding buildings cannot be influenced. Therefore, as a calculation theory of design, not only the stability problem of the supporting structure but also the deformation should be calculated, and the deformation should be controlled within a certain range according to the surrounding environmental conditions. The displacement control of a general supporting structure mainly takes horizontal displacement as main control, and mainly aims to realize more visual horizontal displacement and easy monitoring.
