| 摘 要： | 结合现场采样和三轴试验,以工程中较常见的砂岩为例,设计了不同泡水次数,对砂岩进行了间歇性泡水试验和力学指标测试.通过对天然状态和不同泡水次数下砂岩力学指标的比较分析,研究了间歇性泡水前后砂岩力学性能的变化规律.研究结果表明:随着间歇性泡水次数的增加,砂岩的抗压强度、黏聚力和内摩擦角都呈下降趋势,其变化规律基本符合指数分...

| Abstract: | Combining with field sampling and tri-axial test,and taking sandstone which is common in project for example,different saturation numbers are designed.Then intermittent saturation trial and mechanical index test are conducted.Through comparative analysis of mechanical index of sandstone under natural state and different saturation number,research about the change regularity on mechanical properties of sandstone before and after intermittent saturation is carried out.The results show that: with the increase of intermittent saturation number,the compressive strength,cohesion and internal friction angle of sandstone all show a downward trend and their varying regularities probably conform to an exponent curve. |
