As a Stone Wall Gabion Cages structural system, the foundation pit support should meet the requirements of stability and deformation, that is, the requirements of the two limit states mentioned in the general specification, that is, the bearing capacity limit state and the normal use limit state. The so-called load capacity limit state, for the foundation pit support, is the damage of the supporting structure, dumping, sliding or damage to the surrounding environment, and a large range of instability occurs. The general design requirement is that the support structure does not allow this limit state to occur. The normal use limit state refers to the deformation of the support structure or the excessive deformation caused by the surrounding soil due to excavation, which affects normal use, but does not cause structural instability. The foundation pit support design should have sufficient safety factor relative to the limit state of the bearing capacity, so as not to cause instability of the support, and to ensure the displacement without affecting the safety of surrounding buildings under the condition of ensuring no instability. use. Therefore, as the computational theory of design, not only the stability problem of the supporting structure can be calculated, but also the deformation should be calculated, and the deformation should be controlled within a certain range according to the surrounding environmental conditions
