Research on the Mechanical Properties of Loess in Northern Shaanxi Province and Deterioration Process of Its Mechanical Performance

The regional research is conducted on the mechanical properties and performance of loess in slop northern Shaanxi Province, China. On precondition conforming to related technical regulations, equipment was purchased or selfdesigned machined conduct large-scale in-situ direct shear test participatory a high slope Through multiple field tests red soils four-level platform side engineering tunnel, relation curves stresses two soil types with displacement were comparatively analyzed, change laws strength index rate samples obtained. deterioration development mass revealed through test, thus laying data foundation for analyzing sliding mechanism slopes interaction between anti-slide piles around piles.
