Abstract
To explore the reinforcement effects of different reinforcement methods, kraft paper was used as reinforcement material, and shear tests were carried out in sand to study the reinforcement effects of kraft paper perpendicular and parallel to the shear plane. The test results show that the two reinforcement methods can effectively improve the strength of sand and the orthogonal reinforcement form is more superior. The existence of reinforced materials greatly improves the cohesion of sand, but does not significantly improve the internal friction angle. The width of reinforcement material has little effect on the reinforcement effect and shows different variation laws under different reinforcement forms.
Highlights
Owing to the advantages of easy construction, cost effectiveness, environmental friendliness, and excellent seismic performance compared with traditional materials, geosynthetics are widely used in construction engineering [1,2,3,4,5,6,7,8]
The shear time is a constant concussion of the wrong curve. e shear stress-shear displacement curve [64] for cohesive soils such as loess is very different; the sand particles differ in size, and the cohesive force is almost zero
E shear strength of the sand is in the range of the lower boundary of the shear stress-shear displacement curve
Summary
Owing to the advantages of easy construction, cost effectiveness, environmental friendliness, and excellent seismic performance compared with traditional materials, geosynthetics are widely used in construction engineering [1,2,3,4,5,6,7,8]. To explore the reinforcement effect of different reinforcement methods, kraft paper was used as the sand reinforcement material to study the stress-strain relationship and residual strength characteristics of the reinforced soil under large displacements.
