| 摘 要： | 粉煤灰作为地层时的工程特性研究较少,直接影响粉煤灰场地的勘察与设计.采用钻探、静力触探和十字板剪切试验相结合的方法研究湿排沉积粉煤灰层的工程特性.结果表明:沉积粉煤灰的静力触探曲线呈锯齿状,没有临界深度；锥尖阻力比粉质粘土和细砂小；侧壁摩阻力小于填筑粉质粘土、接近沉积粉质粘土、大于细砂；摩阻比小于填筑粉质黏土、大于沉积... |

| Abstract: | The engineering behavior of fly ash as stratum is studied seldom,which affects directly the exploration and design of the deposition fly ash site.The behavior of deposition fly ash was studied by drilling,cone penetration test and vane shear test.The results of study show that the fly ash cone penetration is the sawtooth form,and there is no critical depth for fly ash.The cone resistance of the fly ash is smaller than silty clay and sand,the friction resistance is smaller than filling silty clay,similar to ... |
