裂隙性黄土力学特性试验研究
An experimental study on mechanical properties of fractured loess
摘要
Abstract
The joint structural plane changes the fine microstructure of loess itself, and it is one of the structure factors of geo-hazards in loess areas, such as ground fissures, ground subsidence, landslide, collapse and loss of soil and water, etc. Taking Shaanxi Sanyuan Q2fractured loess as a case study, the loess fracture specimens with five different fracture angles of 0°, 30°, 45°, 60° and 90° were tested by uniaxial tensile test and triaxial shear test. Both the tensile and shear stress-strain relationships of fractured loess specimens under different confining pressures were discussed, and the tensile fracture and shear fracture characteristics were studied, which is enlightening for further research on mechanism of geo-hazards in geo-environment of loess area.关键词
