The instability of rock slope is still a very frequent geological disaster, which seriously affects people's life and production activities. Previous studies have mainly focused on deformation mechanism, prediction, control hard with single lithology, while there are limited the theoretic computational method stability for soft-hard interbedded anti-inclined strata. In this study, geomechanical model toppling failure soft-hard-interbedded established. modes soft strata analyzed, formula...
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...
Loess landslides are closely related to the variation in mechanical properties of soils due leaching irrigation water area which causes loss soluble salt loess stratum. To investigate effect on characteristics loess, ring shear tests were conducted slip zone soil samples obtained from a typical landslide under different soaking time and concentration. Furthermore, microstructural observations made planes by using SEM (scanning electron microscopy) tests. The experiment revealed that:...
The structure, time-dependent mechanical deformation, and strength characteristics of loess, which is loose porous with well-developed vertical joints, are greatly affected by the dry-wet cycles, attributed to periodic artificial irrigation, rainfall, water evaporation. To better understand creep loess under effect Q2 samples obtained from South Jingyang County, China, were subjected different cycles (0, 5, 10, 15, 20) sheared in triaxial tests. experimental results revealed that: firstly,...
The mechanical properties of the slip zone soil play an important role in evolution loess landslides. To further understand these characteristics, a series ring shear tests was conducted on soils obtained from Tianshuigou landslide, to investigate influence moisture content, dry density, rate and method characteristics soils. experimental results showed that: increase content causes significant reduction residual strength. Specially, both cohesion internal friction angle show deceasing...
Through lithiation and electrophilic substitution of three calix[4]pyrroles, a series new calix[4]pyrrole derivatives were synthesised. The hydrolysed to produce acids and, under base catalysis, esters formed. Thus calix[4]pyrroles with an active functional group obtained. optimum reaction purification conditions investigated. binding properties the anions was examined.
