【摘要】 仁义河特大桥南桥台边坡以石膏角砾岩为主,为了定量分析该边坡的变形、破坏及发展趋势,采集了边坡的软岩试样9组,在室内进行常规三轴压缩试验、单轴压缩流变试验、三轴压缩流变试验及样品试验前后的薄片、电子显微镜扫描分析等,从而揭示了所研究边坡软岩的力学作用规律、微结构变化特征及环境因素的影响等。更多还原

【Abstract】 The south abutment slope of Renyi river great bridge is mainly made up of gypsum breccias. In order to quantitatively analyze the deformation,destruction and developing trend of the slope,9 soft rock samples were collected from the slope site. Then,normal triaxial compression testing,uniaxial and triaxial rheological compression testing were made. The samples were analyzed by thin section and electron microscope scansion before and after testing. Through above methods,the regularity of mechanical action,the characteristic of microfabric change of soft rock,and the effect of environment factors on the soft rocks are revealed.更多还原
