Study on the influence of composite soil on the slope stability of farmland during in land consolidation

To improve the stability of sloping farmland, optimum ratio for parameter composite soils was determined. Plain and mixed were prepared with three improved materials glutinous rice glue, wood fibres coarse sand laboratory to tests experiments. For different moisture soil contents, shear strength, cohesion internal friction angle analysed proportions adjusted based on suitability plant growth. Slope analysis performed in combination case slope farmland improvement. The results show that improvement affected by content, degree influence content strength parameters: fibre > glue plain soil. amendments mechanical properties effectively stability, According total biomass, contents 1.5%, 2.5% 15%. application shows minimum safety factor higher than at slopes 10°, 15° 20°. overall which is suitable
