Description
Technical field
The invention belongs to civil engineering earth building reinforcement technique field, more particularly to a kind of vertical prestressing loam wall and
Its construction method.
Background technology
Traditional cob has cheap, and building technology is simple, the advantages of thermal and insulating performance is good, is typical green
Color environment protection architecture.But because traditional loam wall construction technology is generally using successively tamping, causes cohesive force at layering relatively low, destroy
Form is similar with sheared destruction situation at masonry structure horizontal mortar joint.Therefore, loam wall under action of horizontal seismic due to point
Layer place shear-carrying capacity is not enough and easily occurs failure by shear, how to improve one of shearing strength at intersection performance as rammed earth construction improvement
Individual important directions.
In order to improve wall shearing strength at intersection performance, it is usually taken at building layering and horizontal shear connector is set, but by
Snap-in force is smaller between shear connector and levels rammed earth, and shearing resistance effect is not notable.Understood according to Coulomb theory, work as stress
When shear stress τ in a certain plane of cell cube reaches a certain limit value, along the plane sliding rupture occurs for material.Make material edge flat
The maximum shear stress τ of face slidinguIt can be calculated as follows by acting on direct stress σ on this plane：
τ≤τu=c- μ σ
In formula：σ is that by the direct stress (setting tension as just) on the face of cutting, cohesive strength C and coefficient of internal friction μ are and material
Relevant parameter.Therefore in the case where cutting pressure composite stress state, when the direct stress value on interlayer is bigger, material is less susceptible to along interlayer
Section produces slip.Therefore, the positive pressure value (namely the vertically active force in direction) of loam wall is improved, loam wall can be improved and existed
Shear-carrying capacity at layering.
