祁门县地质灾害及其相似试件力学试验分析
Mechanical Test Analysis of Geological Disasters and Similar Specimens in Qimen County
摘要
Abstract
The mineral content of phyllite has great influence on the strength and fracture failure form of rock.The rock with high quartz content has higher strength and brittle fracture form,which is easy to collapse geological disaster.The strength of rocks with high sericite content is relatively low,shear fracture occurs more often,and landslide geological disasters are easy to occur.Through the mechanical tests of similar specimens of cement,sand and sericite,it is found that schistosity plays a decisive role in the failure of phyllite.When the schistosity inclination is 45°,the phyllite has the smallest compressive strength and is most prone to geological disasters.The addition of basalt fiber can improve the mechanical properties of phyllite,and the experiment shows that the compressive strength of phyllite can be increased by 19.1%.关键词
