In mountainous regions, high-locality landslides have the characteristics of a latent disaster process with wide range, which can easily cause large casualties. Therefore, early landslide identification and dynamic stability evaluation are significant. We first used multi-temporal synthetic aperture radar data to detect potential at Yezhi Site Area during 2015–2020 period, identifying mapping total 18 active landslides. The study area was found an average deformation rate between −15 10 mm/y...
Construction of high-speed railway subgrade on loess soils in the Loess Plateau is risky because such soil susceptible to differential settlements. Various soil-improvement methods have been used enhance mechanical properties loess. Lime-ash and cement-lime are most commonly improvement subgrade, while few studies found by using composite material consisting traditional materials new materials. A series direct shear tests unconfined compressive were conducted specimen with addition three...
The effect of temperature and pressure, which play important roles in the mechanical properties rocks during deep energy exploitation, has not been sufficiently studied previous rock creep models. In order to investigate thermal models, a modified Nishihara rheological model, taking into account coupled damage stress, was proposed by combining theoretical formula for with model. improved model introduces nonlinear viscous dashpot, can accurately describe accelerated phase rocks. To verify...
Abstract. Residual shear strength of soils is an important soil parameter for assessing the stability landslides. To investigate effect rate on residual loessic soils, a series naturally drained ring tests were carried out loess from three landslides at two rates (0.1 and 1 mm min−1). Experimental results showed that displacement to achieve stage specimens with higher was greater than lower rate; both peak friction coefficient became smaller increase in each sample; rates, coefficients all...
Abstract The triggering mechanism and movement evolution of loess-red clay landslides, which occurred frequently along the contact between loess red on Loess Plateau, are closely related to mechanical properties surface. This work presents an experimental investigation loess, interlaminar (LRCI) samples obtained from a typical landslide in northern part Shaanxi province China, using series ring shear tests, microscopic observation scanning electron microscopy attempt explore behavior LRCI...
Triaxial rheological tests are performed on mudstones collected from the soft interlayer in Three Gorges Reservoir Area. In tests, both dry and saturated conditions considered, a complete process is then observed. Based such laboratory observations of stress‐strain, four‐element constitutive model developed, which composed (i) Hook element, (ii) Kelvin (iii) viscoelastic‐plastic body, (iv) nonlinear viscous body (HKCV model). The HKCV adopts one‐dimensional three‐dimensional equations that...
In order to investigate the mechanism underlying formation of landslides induced by irrigation in Heifangtai loess area, Phase2 software was used for numerical simulation typical profile Huangci landslide, and conditions landslide natural saturated states were respectively simulated. The following findings have been obtained through analysis calculation: state, maximum shear strain increment is 0.072, horizontal displacement 0.096m, observed on slope surface; stable at this point. 0.084,...
